On the subject of Waluigi not being in there, Waluigi's Pinball is in the game so, is this the first time that a track that's named after a character has been in the game, while the character themselves isn't?

Baby Park was in DS but there were no Babies.

Bear in mind Baby Park is pretty ambiguous in name, as it doesn't refer to any single entity, while Waluigi Pinball is very much referencing the one character named Waluigi. Not the same situation, but similar.
