Cactus Jack

Cactus Jacks are large, spike covered Pokeys with targets on their chests. They are a paler sub-species of Needlenoses. They can only be moved by being shot by an Yoshi Egg. If they come into contact with anything when rolling, they explode and shoot out coins. Cactus Jacks appear in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, and Yoshi's New Island. They are named after politician John "Cactus Jack" Garner.

Trivia
Cactus Jack's English name more than likely comes from Mick Foley's professional wrestling alter-ego.
