Pirahna Plants are Venus Fly-Trap like plants that originated in the game
Super Mario Bros. They usually pop out of pipes and try to eat the player. They make a brief cameo in
Link's Awakening like many other characters from other Nintendo games. In the side-scrolling view in one dungeon, you have to avoid them by using
Roc's Feather. In this area, there are also
Goombas, mushroom like creatures that are popular in the Mario franchise.
