Crazy Dave

From DYOS Wiki

Crazy Dave is an enigmatic character from the game Plants vs. Zombies who aids the player by giving advice and selling items during the game's progress. He speak in a garbled manner yet his speech balloon displays the English language (or whatever language the game is localized to). He is always shown wearing a pot on his head claiming that "it protects [his] brains from being eaten by zombies".

He has shown up in the DYOS series lampooning one of the advisory tags found in the DYOS wiki, looking around nervously before exclaiming "Buy my crap!!"
