List of Easter eggs in BTD6

This is a list of Easter eggs found in Bloons TD 6.

Main menu

• Interacting with the Monkey Town Hall causes a Ninja Monkey to jump out from behind it, then vanish in a puff of smoke.
• Interacting with the Windmill causes a Monkey Ace to fly through it.
• Interacting with the fountain statue causes a monkey to peek from behind it.
• Interacting with the hut on the left causes two Bomb Shooters to pop out of the left and right huts. The left one shoots a cannonball, the right one catches it and shoots it back, the left one catches it, then they both disappear.
• Interacting with the tree on the left causes a Boomerang Monkey to pop out, throw a boomerang, then disappear.
• Interacting with the water in the bottom-right corner causes a Monkey Sub to wave and float by. During Halloween, it is replaced with a Pirate Lord.
• During a Fireworks Collection Event only, interacting with the fireworks on the beach sets them off.

Maps

Adora's Temple

• 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.

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.

Example setup

Myrkul

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

• This map contains a hidden removable: on the dam, there are two panels which each reveal a button underneath after being interacted with five times. If both buttons are revealed and then pressed, a large button is revealed in the center. 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

• A player can free the Cave Monkey by hitting it with 30 Mortar Monkey projectiles to break the ice.

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.

Spa Pits

The map has a secret that changes its appearance and layout to be more like Tar Pits. It can only be activated 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 utilized 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 mobile version of Bloons TD 5, unlike in the Flash version, where the paths alternate directions based on the round and the pits can be placed on.

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. This can only be activated 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

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.

Underground

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