Crazy Dave's Twiddydinkies

​ Not to be confused with Crazy Dave's Car.

Crazy Dave's Twiddydinkies is Crazy Dave's shop, and is located in the trunk of his car. The player gains access after finding his Car Keys at the end of level 3-4. On iOS versions, the Car Key is given to you by Crazy dave after More Ways to Play is unlocked on level 2-2. Once in every level set (Fog and Roof) afterwards, new merchandise will be added. The player can purchase more seed slots, plant upgrades, new defenses for the Pool and the Roof, Zen Garden items, upgrades, various House Blueprints (XBox and PSN only), and Mini-game Packs (iOS only).

In the Xbox Live Arcade and Playstation3/ Playstation Vita version, Crazy Dave will give you "CRAAZY DEALS that you'd have to be dead to turn down!" It is unclear what these deals actually are as no one has confirmed getting one yet. When obtained they might show up in your Mail.

Extra Seed Slots

Trivia

 * Somehow, all the items you can buy fit in Crazy Dave's trunk.
 * If you stay long at Crazy Dave's Shop without doing anything, he might say any of the following:
 * "I eat food off the floor!"
 * "ACT NOW! I'M CRAZYYYYY!!!
 * "All Twiddydinkies are priced to move!"
 * "Our prices are unbelievable!"
 * In the trunk of Crazy Dave's car, the title War and Peas can be seen, a reference to War and Peace, a Russian novel by Leo Tolstoy.Warandpeas.png
 * It's also a reference to ZomBotany, as in the Lawn Strings, ZomBotany Mini-games are labelled 'War and Peas'.
 * It could also refer to how the Gatling Pea has an army helmet and references going to the army in the Almanac.
 * In the Xbox 360 and PS3 Versions of the game, Crazy Dave's License Plate says various lines instead of "Menu", "Main Menu" and "Go Back".
 * Some lines include MEAMDAV ("Me am Dave"), SODALID ("Soda Lid"), VRM VRM ("Vroom Vroom"), SMTNFNY ("Something Funny"),UN EMPLD (Unemployed), MAD4GRVY ("Mad for Gravy"), FLOR FUD ("Floor food"), and RDWARER ("Road Warrior").
 * The Xbox 360 and PS3 Versions also include another section in his car, devoted to selling Blueprints to various houses.
 * After buying a Level five Blueprint from Crazy Dave, the Blueprint will say "Sold Out" but the price will increase by $8,000. It is unclear if PopCap intends to bring even higher tier Blueprints to the game later in the form of an update or DLC, or if the system is just set to add $8,000 each time.
 * This also happens with seed packets on versions that have only nine seed slots. After you buy the ninth the price will bump up to $80,000. The price of the tenth seed slot in the games that have all ten.
 * In Crazy Dave's Car Trunk, you can see a figure of Lex, who is the protagonist of Bookworm, another game by PopCap. Lexbookworm.png
 * The item that costs the most is the upgrade to ten Seed Slots which costs $80,000.
 * It is unknown how there can be multiple sections of the store in a single trunk.
 * Perhaps in game to keep it organized but in reality (to them) it's all over the place.
 * The background of the Shop changes depending on your Level progress. If you are playing day levels, the background will turn into a day background, and when you play night levels, the background will turn into a night background.
 * There are Rollerblades in his trunk for some reason.
 * On the iPhone and iPod Touch, the shop is obtained when More Ways To Play is unlocked on level 2-2 so you can buy Mini-games. Other things do not appear until the Bacon is obtained on level 3-4.
 * It is unknown whether the Bacon is anything but a waste of cash. When it is bought for $500 all that happens is he makes a weird face at you and says "MMMMMM DELICIOUS!" (This is only on the iOS versions).
 * In the PC trial version, there is Plants vs. Zombies Full Version item in the shop.
 * It is odd how the cheap things in real life (Seed Packets and Pool/Roof Cleaners) cost a lot more in Crazy Dave's Twiddydinkies, but the more expensive things (House Blueprints and House Changing) are very cheap in real life.
