Ninja Abode is a building in Bloons Monkey City. It increases your Ninja population by 1.
The Ninja Abode looks similar to a Japanese house and has 2 shurikens on the roof. The building changes when tier-4 upgrades are unlocked. When both 4th Tiers are unlocked, the main roof turns black along with the front wall. When only one is unlocked, a shuriken is above the doorway and the front wall is bluish-whitish.
The Ninja Abode's resident looks like a Dart Monkey Hall's resident, but wearing a red shirt and places its arms at its mouth.
