Visually, it is a greasy strip of fried pork, which Crazy Dave will exchange for a diamond. This is similar to the Magic Taco, which is obtained in Level 4-4 on all versions and then also given to Crazy Dave for a diamond. When given the bacon, he will exclaim:
"YOU FOUND MY BACON!!! My sweet oily bacon! I'll give you $1000 for it! Now I'm going to rub the bacon ALL OVER MY FACE!!"
The bacon can also be unlocked in the shop after buying the ninth seed slot and it will cost $50. When it is clicked on, a message will appear saying: "It won't help against the zombies, but everyone loves bacon!" After the first purchase, the bacon's cost will be raised to $500. Then a new message will appear when the player taps on the bacon, and it will say: "Mmmmmmm... Delicious!" When bought, Crazy Dave's eyes get very big and he will also say "Mmmmmmm... Delicious!" Purchasing it after that will yield no reward for the player as it is just a clever way to lure them out of $500. Therefore, it is highly not recommended to purchase bacon.
