Electroids

Little Blue Creatures make their first appearances in "Memories of Boom Boom Mountain." There are at least six of them, and they get into an argument with Plum Frog. They accuse him of stealing their triangle, while Plum Frog defends and says that the little blue creatures took his plum. Finn eventually works out a plan so that the little blue creatures get their triangle back. In "When Wedding Bells Thaw," one of the little blue creatures can be seen. They have a total of 4 lines-one is,"That guy stole our triangle!". The other three are when they are cheering after getting their triangle back, where they say,"Ya-hoo! Yeah! Yay!"

Appearance
The Little Blue Creatures have been seen neon cyan, indigo, grey, and ordinary blue-colored. Their entire head and torso is composed into a sphere. Their limb joints are marked by circles. Whether they have arms or legs varies.
