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 Key at the end of level 3-4. On iOS versions, the Car Key is given to the player 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 Live Arcade and PlayStation Network only), and Mini-game Packs (iOS only).
In the Xbox Live Arcade, and PlayStation 3, and 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 the player's Mail.
Extra Seed Slots
These can be purchased at any time, as soon as the previous one has been purchased. They can also be purchased before the shop is unlocked, as whenever the player has enough money for the next one at the end of a level, Crazy Dave will appear and give him or her the choice to purchase it.

- Somehow, all the items the player can buy fits 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 CRRRRRAAAZY!
- "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.
- In the Xbox 360 and PlayStation 3 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").
- 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 downloadable content (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 the player buys the ninth seed slot, the price will bump up to $80,000, the price of the tenth seed slot in the versions that have all ten.
- In Crazy Dave's Car Trunk, a figure of Lex, the protagonist of Bookworm, another game by PopCap, can be seen.
- 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. This may have been done 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 the player's level progress in Adventure Mode. If he or she is playing Day, Pool, or Roof levels, the background will turn into a day background, and when he or she plays Night, Fog, or Night Roof levels, the background will turn into a night background.
- There are Rollerblades in his trunk for some reason. Also, in the iPad version, there is a brain in his trunk as well.
- On the iPhone and iPod Touch, the shop is obtained when More Ways To Play is unlocked on level 2-2 so the player 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 the player and says "MMMMMM DELICIOUS!" This is only on the iOS and Android versions.
- In the PC trial version, there is the full version of Plants vs. Zombies Full Version item in the shop.
- It is seemingly odd how the cheap things in real life (Seed Packets, Pool Cleaners, and 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. This may demonstrate his craziness.
- The Imitater is the only plant sold in Crazy Dave`s Twiddydinkles that is not an Upgrade Plant.
