This paper toy is the Crazy Dave, the deuteragonist in the video game Plants vs, Zombies, the papercraft was created by Blank Canvas. Crazy Dave wears a saucepan on his head, presumably to protect his brains from being eaten, but maybe just because he's crazy. During Adventure Mode, Crazy Dave serves as a sort of narrator, introducing the player to certain levels and explaining some of the Mini-games and Bonus Levels. He is later abducted by a Bungee Zombie on level 5-10 right before he can tell the player Dr. Zomboss' weakness. He also has a shop called Crazy Dave's Twiddydinkies that he runs from the back of his car, once the player finds his car keys. He sells several plant upgrades, extra defenses, and Zen Garden items.
When re-playing Adventure Mode, Crazy Dave will randomly pick 3 of the player's plants for each level, which can't be switched out, but quitting and reloading the game makes him choose three different ones.
Crazy Dave is probably based on a series of commercials in the 70's and 80's for a consumer electronics company in the northeastern United States. Jerry Carroll, a popular radio disc jockey, played the frenetic host with the memorable slogan, "Crazy Eddie, his prices are IN-SA-A-A-A-A-ANE!". It should be noted that Jerry did not actually play Crazy Eddie, but always referred to him in the third person view.
