It's the stuff of fan-fiction for sure: Falco, from Star Fox, has to go through wave after wave of "badniks" from Dr. Robotnik's Mean Bean Machine in order to save the princess, Peach from Super Mario Bros to be exact. Oh, and not only is Falco sporting all his moves from Super Smash Bros, but everything he does nets points (plus Sonic's ring make an appearance here and there).

According to the source, the music accompanying the action is also from Sonic, as well as Pokemon, though sounds of the San Diego Fair makes it hard for me to make anything out. But I'll take GoNintendo's word for it.
