- Why? BECAUSE I'M CRAAAAAAAZY!
- — Crazy Dave
Crazy Dave is the deuteragonist in the Plants vs. Zombies series. 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 (after level 3-4). He sells several plant upgrades, extra defenses, and Zen Garden items. He is never seen without a pot on his head.
When re-playing Adventure Mode, Crazy Dave will randomly pick three of the player's plants for each level, which cannot be switched out, but quitting and reloading the game makes him choose three different ones.
Crazy Dave will buy a Magic Taco, found only on level 4-4 of the first play-through of Adventure Mode, for $1000. He will also reward the player with two Marigolds of random colors when the Zen Garden is unlocked, as well as five bags of fertilizer. Marigolds cost $2,500 at Crazy Dave's Twiddydinkies and a five-pack of fertilizer is only $750.
Crazy Dave appears in Plants vs. Zombies 2: It's About Time after beating Player's House - Day 4. After the player gets a hot sauce, he wants to borrow for his taco. He said it was amazing and he wanted to eat it again. To do this, he has a new friend named Penny, a time machine that can travel through time. After that, the real trip has started, first in Ancient Egypt.
- Crazy Dave is based on real-life game designer and former PopCap employee David Rohrl. The sandaled feet, scruffy facial features, and even the car cluttered with board games are all nods to Rohrl's own peculiarities. Rohrl still frequents PopCap parties with a pot on his head. He is acknowledged as a "Special Thanks" in the Plants vs. Zombies credits.
- In the credits song Zombies on Your Lawn Crazy Dave is seen being held upside-down by a Bungee Zombie (probably the same one as in 5-10), but his pot does not fall off his head.
- There are only five times the saucepan is ever seen off his head in the entire game. The first is while he is introducing Level 1-5. The second is when he recommends the full game in the free trial. The third is after buying the Magic Taco in Level 4-4. The fourth is when you buy the last plant from his shop and he gives you the achievement Morticulturalist. The first four times, he says "BECAUSE I'M CRRRRRRRAAAAAZY!!!", his saucepan flies up in the air, does a flip, and falls back on his head. The only other time the saucepan is off his head is when he is kidnapped by the Bungee Zombie before battling Dr. Zomboss, when his pot is seen tumbling to the ground.
- In the iPhone/iPad versions, his hat comes off each time he gets bacon.
- Also in the iPhone/iPad versions, his hat comes off at the end of his speech when he introduces Last Stand.
- In Plants vs. Zombies 2: It's About Time, his hat comes off after he eats his taco, in the dialouge before the battle with the Zombot Sharktronic Sub, and in the dialouge when he introduces Tiki Torch-er.
- If the player hangs around long enough in his shop without doing anything, he might say random things, such as: "I eat food off the floor!"
- He says four random things: "I eat food off the floor!", "ACT NOW! I'M CRRRRRRAAAAAZY!!!!!", "All Twiddydinkies are priced to move!", and "Our prices are unbelievable!!!"
- In the last level, before he gets abducted by the Bungee Zombie, while trying to recall Dr. Zomboss's weakness he mentions the Konami Code (up, up, down, down, left, right, left, right), but he quickly realizes it is the wrong thing and moves on.
- The code, (up, up, down, down, left, right, left, right, B, A, [an alternate version of the Konami code]) if entered in-game, a popping sound is heard.
- An easter egg in Valve's Left 4 Dead 2 in The Passing can be found in the Underground level. It contains graffiti that says "Looking for an M60? Come see me. - Crazy Dave".

- According to the game sprites, there is a Crazy Dave Zombie, which is actually just a larger version of the Bungee Zombie's sprites, used for the Bungee Zombie that abducts Crazy Dave. This is so the large Bungee Zombie that abducts Crazy Dave doesn't appear blurry or pixelated.
