Koro sensei

Intro Height: 9’10, Weight: 300kg (661 ibs)Korosensei has the appearance of a yellow octopus who is about three meters tall and possessed a large, bulbous head with a large smile that rarely breaks or moves, and small, beady eyes. He uses two tentacles as arms, each having two feelers as fingers, and utilized the rest of seemingly jelly-like limbs - his tentacles - to walk. Korosensei has a pair of hidden nostrils, which make him appear to have four eyes if detected. Due to his constant grinning, he changes his color to express his emotions. Korosensei wears a black academic dress, a small black squarish mortarboard cap with a yellow tassel and a large black tie with a yellow crescent-shaped moon on it. Can potentially make tentacles spawn from the ground? Can stretch his tentacles as long as he wants?
