From what I remember, the tank appeared in a episode where they were spying on several of the other characters in school, and that Ocho did a cheat code to make a ? mark block from Mario appear so he could get money for a vending machine. Shortly after, Gumball tries the same code and spawns said tank, causing the episode to crash for a little while. I think it was the same episode where they discover how that toast character kept coming back to life.

Also, another glitch I found was that when Gumball bumps into opponents during Carrie's Possession, the opponent still has a second to react, so they normally block it, or duck, making the rest of it miss.
