Pokeys are cactus enemies that are typically composed of three to five spherical body segments. To defeat a Pokey, typically each body section must be destroyed; however, defeating the head usually kills the entire enemy. Pokeys, along with Ninjis, Shy Guys, Bob-ombs, and Birdo, originate from the non-Mario game Yume Kōjō: Doki Doki Panic, which later became Super Mario Bros. 2.
