Crazy Dave's Car Key

The Car Keys are obtained at the end of level 3-4, and belong to Crazy Dave. When obtained, they unlock Crazy Dave's Twiddydinkies, a shop in the trunk of his car. If the player doesn't have the full version of Plants vs. Zombies he or she will only be able to access a few things in the shop. This is also the last thing a player can unlock if s/he doesn't have the full version.
