Raccoon Koopa
Raccoon Koopais a powered-up form of King Koopa. This special form is similar to Mario's Raccoon Mario form.
The Raccoon Koopa form has only appeared in The Adventures of Super Mario Bros. 3 episode "Super Koopa". In the episode, Koopa, through the use of a powerful pendant, gained the ability to conjure and use Power-Ups, including Super Leaves.
After becoming Raccoon Koopa, Koopa gained a long, raccoon tail, as well as raccoon ears. Using his tail, Koopa could attain flight. As Raccoon Koopa, Koopa possibly became physically more powerful, as he was able to punch a helicopter out of the sky with his bare fist.
Eventually, King Koopa lost his ability to turn into Raccoon Koopa after his pendant overloaded and exploded, due to using too many transformations in a row.
