Regrow Bloon
Applies to All regular Bloons

Regrow Bloons are a type of Bloon property in Bloons TD 6. These heart-shaped Bloons regenerate lost layers every 3 seconds. All Bloons up to Ceramic Bloons can have this property. In standard gameplay, Regrow Bloons first appear on Round 17, or Round 3 of Alternate Bloons Rounds.

If a Regrow Bloon splits into multiple Bloons when popped, they can multiply if their children are allowed to regenerate. Regenerated layers do not generate cash or add to the damage count of towers if re-popped, but do count towards pops needed to unlock towers from the Gift Box. They cannot regenerate while under the effects of Grow Blocker or Ezili's Heartstopper, or if they are frozen. Regrow status can be removed by attacks that can strip Regrow, such as Heart of Oak, Cleansing Foam, or Corvus's Haunt effect. Certain upgrades, such as Gyrfalcon, deal increased damage to Regrow Bloons.

DDTs, Dynamite Bloons, and Glass Bloons release Regrow Bloons when popped, but they cannot regrow back into DDTs, Dynamite Bloons, or Glass Bloons, respectively. If a Fortified Regrow Bloon pops and regrows back to its initial layer, it does not restore the Fortified modifier.

The final round that actual regrow bloons spawn is Round 79 in Standard Rounds, or Round 74 in Alternate Bloons Rounds. Not counting Rounds 81+ because regrow property gets useless due to freeplay rules that regular bloons only spawn 1 bloon and ceramics having 60 (120 for fortified) health at that point.

The round with most amount of regrow bloons is Round 95 in both Standard and Alternate Bloons Rounds, although DDTs are the main threat at that point.

Tips

This strategy section is empty or incomplete. See the strategy guidelines for more information on how to write strategy sections. The editor who added this notice elaborates: list examples. Please don't recommend regrow blocker or heart of oak because those suck and are unnecessary except in challenge editor

This section was last updated for: version 53.2

• Towers should have enough pierce, attack speed, and damage to avoid Regrows from overwhelming the player.
• Starting from round 31, multi-child Regrows appear, which are capable of producing infinite children if not popped quick enough.
• Most de-Regrow or grow-blocking options simply aren't worth the cost compared to just having enough pierce and damage.
