An object that Mario can climb up or down like a vine. It makes a "buzzing" sound as you climb, as though Mario is repeatedly hitting his head on something. It can still be placed in-game with a level editor. Although it appears as a brown flagpole ball, the actual 16×16 metatile that is used is unique to this object. According to the leftover source code from the All-Stars version this object is internally known as Wood-3, meaning that it was meant to be attached to the trees located in the Tree levels
