Boss guide
The Amoeba Droid will drop down into the blue chemicals below and collect it, creating an impenetrable barrier. It will bounce along the ground three times. Afterwards, it will hover in the air spinning small spheres of the chemicals around it. Though the Amoeba Droid can be hit in this state, it may still hurt the player. It will eventually release all its chemicals, leaving it completely vulnerable. After six hits, the Amoeba Droid will be defeated.
