Porcupo is a species of a porcupine who appears in Yume Kōjō: Doki Doki Panic and Super Mario Bros. 2. As it appears, Porcupo harms the player by touching him/her with its spikes on it. It simply walks back and forth waiting for a victim to come by. A Porcupo can be defeated in two ways; it can be injured with a vegetable or another enemy thrown at it. It can even be defeated by a starman.
