Sag niemals Holerö!
In the Mario comic titled Sag niemals Holerö! published on the german Club Nintendo magazine, Mario has to fight an evil alien that's transforming every person on earth into food using a magical song. He, a Toad named Todojewski, T.T. and Bomberman are of the only ones not to be effected by the song, as they're said to be the chosen ones to fight the alien.
Since the comic takes place in northern Europe, T.T. is said to be from Zurich, Switzerland, and is called Tic Toc. However these differences are just for storytelling reasons, so despite them, this can be considered an actual, official incarnation of T.T.
