I came accross this over at 1up.com. Apparently Pacman and other videogame characters are inspiring Spore creature makers.

Spore, the next and arguably most ambitious project from Sims mastermind Will Wright, has a sneak preview of sorts with the recently-released Spore Creature Creator. Although only one piece of the total Spore experience, players have quickly taken to creating their own cuddly creatures, creepy crawlies, and abominations. Aside from penisaurs, the first thought to a lot of gamers was to pay homage to their favorite games and franchises with their creations.
