Stony Banjo is the native transformation of Mayahem Temple. This form can get through small passageways, but its true value lies both in its ability to understand other Stonies' language and to enter the kickball stadium in order to play for a Jiggy. Apart from Dragon Kazooie, the Stony is the only transformation in Banjo-Tooie that can traverse worlds, since he's needed to play kickball in Hailfire Peaks as well but you can't leave the stadium as Stony Banjo. You need to change back in order to go outside. His shoulder charge attack is useful both for attacking enemies and grabbing the opponent's ball in kickball.  


Being much smaller than regular Banjo, Stony Banjo is solidly rock (he is a stony now, it's in the name description.), with a much bigger head than the rest of his body. Like other transformations, he keeps his book bag and shorts. Because he can't move his unjointed legs, he hobbles along, but he is still surprisingly fast and agile.
