Appearances in the Series

They are first seen in The Infamous Amoeba Boys, where there is a flashback shown at the beginning of the episode where they are still water, but been hit by the black aura and become monsters. Weeks later, Poochi detected an aura of them and called the Powerpuff Girls for help.  The Powerpuff Girls were searched for the group until they got tired while the Amoeba boys were in the bank waiting for there turn to called.  They missed their number and meanwhile a kid is making fun of them. And Lady is mad at the kid. The guard saw them ramping a bank so he decided to kick them out.  The girls told them to return to normal by sending them to Professor but Silk Hat told them, you can't catch big villain, and so they complain to each other. They heard a dog voice and been return to normal.  And that day, they are not been catch by those girls instead hiding in underground.


Their weakness is the pink dog named Koyuki-chan (In Japanese).


They can combine to each other (becoming very large) but no super power to attack but they can only jump up and down. However, their sheer size is enough to make them dangerous when combined.
