This defensive housing allows monsters to fight to death defending your base.

Building Information

The Monster Bunker, being a defensive tower, differs from conventional towers in the game as its mode of attack is to release monsters that have already been bunkered in it beforehand. Monsters can be sourced from the player's current Housing though a variable amount of Putty. Alternatively, they can also be bought with Shiny from a store within the Monster Bunker. However, monsters that have not been unlocked in the player's Monster Locker cannot be purchased. Upon detecting hostile monsters entering its range, it will release bunkered monsters onto the yard. Bunkered monsters will then seek out the responsible hostiles and attack them. Hostiles under attack from bunkered monsters will switch targets to its attacker while nearby ones will join the fray. Both sides will then battle until either side is victorous. If the defenders survive, they will return to their Bunker, where all survivors are returned to full health at no cost. Bunkered monsters that were killed will be removed and will free up space in the bunker for new monsters. The Putty cost can be calculated with this formula:

(Goo cost x Amount of defined monster) ÷ 2 = Putty Cost

Place the monster bunker near the silo or town hall. Place as deep as possible in the base as most people will try to bait it.

NOTE: Bunkered Eye-ra's will self-destruct while defending, so you will have to replenish them every time they are released. Damaged or destroyed bunker can't release monsters!

  • The level 1, level 2 and level 3 bunkers' capacity is equal to level 4, level 5 and level 6 of the Monster Housing's capacity.
  • If you don't have a monster juicer, go to the bunker and you can see "kill 1" althrough you can't see that they kill themselves and you will not get any goo.
  • Even the bunker is full, it can still fit one pokey,but it will lose a monster. Example: 4 D.A.V.E.s will become 3 D.A.V.E.s so don't put any pokey in there if it is full.
