King Bu is Da Mushrum Kingdum equivalent to King Boo, a world renound retard.
Super Malleo SunshineEdit
Super Malleo Sunshine is the game King Bu made his first appearance. He used his ability, THE BAGEL!!!!!11!!1one!, to destroy Malleo so he can rule Da Mushrum Kingdum for himself.
Weegee's Mansion is the last game he appeared in. When Weegee confronted him, Weegee turned him into a Weegee and ordered him to jump off a clif, therefore killing himself.
