A very friendly, very tall, red-colored friend with a stubby left arm and crooked left eyestalk (which he describes as "wonky"). However, in "Good Wilt Hunting", it is discovered that he was not always this way; he was injured in a fateful accident during a basketball game, leaving his arm crushed and his eye injured. Wilt exhibits consummate good sportsmanship, which he applies to every part of life he can. He is considered the nicest person at Fosters and he's extremely courteous to a fault, often willing to help anyone, fix anything, and perform anything asked of him, (even if he has to go entirely out of his way to do so), and apologizes almost constantly (he is known for saying "Is that okay?", "Sorry!", "I'm sorry, is that okay?", and "I'm sorry, but that's not okay!"). He has a big heart, is cool and collected, and on very rare occasions can be moody or short-tempered. His name is a homage to NBA star Wilt Chamberlain. Wilt was shown to be created by Jordan Michaels, a basketball star (and a homage to Micheal Jordan). His oversized basketball shoes always squeak against the floor/ground, no matter what surface he is walking on. He is voiced by Phil Lamarr.
