A frightening creature that can bounce like a giant rubber eraser, and swipe along the ground to 'erase' scientific and social progress, returning civilised areas into barbaric ones.
ABILITIES:
Gumi-Bounce: can bounce up and down but strangely causes no tremors
Gumi-Erase: clears all scientific and social progress away as it wipes over ground
Gumi-Flash: eyes flash to summon intelligent abstract shapes that can erase on a smaller scale
