Johnny Test games are games based on the Cartoon Network character, Johnny Test. A couple of the popular Johnny Test games are "Johnny's Deep Sea Snapshots" and "Attack of the Johnnies."
In "Johnny's Deep Sea Snapshots," Johnny Test is on a quest to find gold while avoiding exploding canisters and biting fish. The players use a camera to scare away the fish. The longer the camera charges, the more space the flash covers to scare away fish.
"Attack of the Johnnies" pits players against clones of Johnny Test. The players buy defensive machines to kill the clones before they reach the protons and steal them.
