• During a Fireworks Collection Event only, interacting with the fireworks on the beach sets them off.
• During a Christmas Collection Event only, interacting with the presents under the tree makes a sleigh bell sound.

Maps

Adora's Temple

Many sacrifices are required to change the theme of this map.

• The Monklish on top of the temple reads "MAX SDN" and "APEX DARK".
• If Adora is placed and transformed into her Vengeful form (by creating a VTSG with her in its range), the map changes to a dark version with red water. This remains even if Adora and/or the VTSG are sold.

Another Brick

• Interacting with the pigeons (bats during Halloween Collection Events) causes them to fly away, then return after a few minutes.

Bazaar

• The Monklish on the tea stall's sign reads "KL TEA CO".
• The Monklish on the building's sign reads "CLOSED".
• Interacting with the basket by the tea stall repeatedly causes a kiwi bird to pop out.
• Interacting with the lamp in the bottom-right repeatedly causes a spirit to pop out.
• Interacting with the cat in the cat stall repeatedly causes it to meow.

Blons

• Interacting with the pigeons causes them to fly away and return after a few minutes.

Bloody Puddles

• Interacting with the tree on the top right corner causes a kiwi bird to come out and walk to the bottom right of the screen.

Bloonarius Prime

• Repeatedly interacting with the left corner of the rightmost lake causes a crocodile to appear.

Candy Falls

Interacting with certain spots of the map reveals an Oompa-Loompa monkey and triggers a generic sound cue. Interacting with the one in the the top right corner plays a different sound cue that begins the sequence of the Oompa-Loompa theme. Once the player triggers this, interacting with the other Oompa-Loompa monkeys in a specific order plays the rest of the first line of the Oompa-Loompa theme song in A minor, and unlocks the Golden Ticket achievement.

1. The top right corner
2. The door of the house
3. The chocolate waterfall
4. The top left corner
5. The right side of the chocolate river, between the middle and lower lanes of the track
6. The bottom right corner
7. The watermill
8. The bottom left corner

Selecting the wrong Oompa-Loompa monkey or not selecting any of them for a few seconds triggers different sound cue. Doing this breaks the sequence, and the player needs to start over.

Carved

• Repeatedly interacting with the cauldron causes it to jump and produce a beam of light.

Dark Dungeons

• Repeatedly interacting with the bottom-left corner of the sludge pool causes a monster to pop out. Interacting with it again causes it to return to the pool.

Encrypted

Example setup for summoning Myrkul

Myrkul

• Selecting one of the four headstones on the far left and far right sides three times causes a skeleton arm to pop out of the dirt.
• Selecting one of the two headstones in front of a puddle three times causes a fish skeleton to jump out of the water.
• A player can summon a secret tower named Myrkul on the altar by performing the following steps:
  1. Place a Super Monkey on the altar.
  2. Place a tower on each of the four tower category pedestals and upgrade each of them to any tier 5 upgrade.
  3. Place a Primary tower in front of the bottom left grave, a Military in front of the bottom right grave, a Magic tower in front of the middle left grave, and a Support tower in front of the middle right grave.
  4. Upgrade the Super Monkey on the altar to a Sun Temple. It will sacrifice all towers on the tower category altars. After a short pause, the Sun Temple is sold and all of the altars collapse, with Myrkul taking their place.

Flooded Valley

Flooded valley can indeed be flooded.

• This map contains a hidden removable, revealed by interacting with the two panels on the dam:

1. Press the top panel five times, revealing a button.
2. Press the bottom panel five times, revealing a button.
3. Press the top button.
4. Press the bottom button.

A large button will then be revealed in the middle. Interacting with the large button gives the option to pay $5,000 to cause a dam breach. This floods almost the entire left side of the map, filling it with water and forcibly selling any non-water towers which get flooded.

Frozen Over

• Players can free the Cave Monkey by hitting the ice above it with Mortar Monkey shells 30 times. Once released, it jumps out of the ice and lands on a random area near the entrance of the track. In Co-op, it becomes owned by the lowest-numbered active player (i.e. player 1, unless that player quits).

Hedge

• Interacting with the statue causes it to rotate.

High Finance

• Interacting with the crane causes it to rotate.

Logs

• Interacting with the mushrooms causes them to shake, and release spores if done repeatedly.

Lotus Island

• Creating the VTSG on the stone podium turns all the flowers purple and the pollen orbs dark red. This increases the stun duration of the pollen bursts to 5 seconds, or 2 seconds for MOAB-Class Bloons.

Luminous Cove

All three carvings glowing and the seaweed removed

The uncovered area

• Interacting with the seaweed on the carving removes it.
• If a Mermonkey is upgraded to one of its 5 upgrades (Lord of the Abyss, Popseidon, or The Final Harmonic), causes the corresponding carving to glow. The glow does not disappear if the Mermonkey with that upgrade is sold or otherwise removed. Lighting up all three carvings makes it interactable. Once interacted with, the carving sinks and reveals extra water space.

Midnight Mansion

• The Monklish on the upper hallway reads "STOP".
• The Monklish on the stairs reads "NOWAY".
• The Monklish on the lower hallway reads "NOMONKE".

Middle of the Road

• The Monklish on the signs by the windpump reads "END" (pointing to the right) and "START" (pointing to the left).
• The Monklish on the road sign reads "US" (in reference to U.S. Route 66).
• The Monklish on the pickup truck reads "CHV".

Quarry

The three cracked wall segments

The uncovered fossil and egg

Interacting with certain background objects plays a sound effect and spawns dust particles. Interacting with them in a specific order plays a sound cue and causes parts of the wall to crack. There are three combinations:

• Left part:
  1. The cross on the right side of the upper wall
  2. The rock by the end of the lower channel
  3. The upper rock in the upper stream
• Middle part:
  1. The cross on the left side of the lower wall
  2. The topmost rock on the rock tower on the right
  3. The lower rock in the upper channel
• Right part:
  1. The cross in the middle of the lower wall
  2. The rock on top of the exit
  3. The rock in the middle of the lower channel

After cracking all three parts of the wall, repeatedly selecting part of the wall breaks it, revealing a fossil. After breaking all three parts of the wall, interacting with the upper waterfall reveals an egg.

Resort

• Interacting with one of the umbrellas closes it, and interacting with it again reopens it.
• Interacting with the palm tree on the bottom-left corner makes a rustling sound and reveals a crab.

Skates

• Interacting with the penguins at the top of the map causes them to dive into the lake below, then return after a few minutes.

Skull Tweak

Interacting with the water spots in front of the skull makes the map harder by changing the entrance to the two eyes of the skull. Interacting the following spots before starting the first round changes the map layout and transforms it into Party Peak, as well as changing the map's default music track to Tribes - Jaloon:

1. The bottom-left water quadrant
2. The top-right water quadrant
3. The top-left water quadrant
4. The bottom-right water quadrant
5. The bird nest

Spa Pits

Interacting with rocks makes the map much harder and reminiscent of Tar Pits.

The map has a secret that changes its appearance and layout to be more like Tar Pits. The player can only activate it before starting the first round (making it impossible to activate in Apopalypse).

Interacting with the loose rocks blocking the four inactive entrances/exits, in the order indicated by the number of scratch marks on the rocks (bottom-left, top-right, top, bottom-right), causes a prompt to appear asking "Make map heaps harder?". If confirmed, the path around the center pit will disappear, splitting the layout back into five small clockwise loops used by all five entrances/exits, and the five outer hot springs turn into tar, which renders them unusable for tower placement and sells any towers that were originally placed in the water. While now unused by the Bloons, the path around the center pit is still considered a valid location for on-track projectiles such as Bloon Traps. Sauda's Sword Charge is modified when the secret is enabled; it now only uses the five short lanes instead of the long single lane.

The harder version is based on its layout in the multiplatform version of Bloons TD 5. It differs from the the Flash version, where the paths alternate directions based on the round and the player can place towers on the tar pits.

Sulfur Springs

Interacting with the geysers triggers animations and sound effects. Interacting with them in a specific order plays a special sound cue on each interaction, and interacting with the last one causes them all to erupt. The player can only activate this once per game.

1. Top left
2. Top right
3. Bottom right
4. Bottom left

Tinkerton

• Interacting with the tree in the top right causes an orange to fall and a drone to pick it up and fly away.
• Interacting with the whiteboard turns it over. The front side says "TO DO" in Monklish and has a drawing of Rosalia's head and an orange slice. The back side has "SOLVE:" in Monklish, the equation "2+2=???", and a drawing of the square root of a pie.
• Interacting with the book by the window opens it for a few seconds.

The Cabin

A popular antagonist could chase the car when removed.

Interacting with certain background objects triggers animations and sound effects. Interacting with them in a specific order, then removing the car, triggers a special animation where a monkey wearing a hockey mask pops out of the cabin and chases after the car.

1. The door to the cabin
2. The right side of the bridge
3. The middle of the bridge
4. The left side of the bridge
5. The bat to the left of the bridge
6. The tire swing
7. The axe to the right of the cabin

Tree Stump

• Interacting with the axe causes it to chop the log.
• Interacting with the mushrooms causes them to shake, and release spores if done repeatedly.

Tricky Tracks

• The Monklish on the side of the middle track's platform reads "XLGamer10", and on that of the blocked track, it reads "VillainSeven". Both are references to the co-creators of the original map.
• The Monklish on the back wall reads "ZOMG" and "ZJ was here."

Underground

• Interacting with the bats causes them to fly away, then return after a few minutes.
