Golden peg

Golden pegs (also referred to as tiny lamps) are bolt-like protrusions in the ground in Super Mario Galaxy and Super Mario Galaxy 2. Firing a Star Bit at one with the Star Pointer turns it into a collectible coin. Golden pegs are present in some boss arenas, such as the ones for Dino Piranha and Topmaniac. Golden pegs are also present on the Battlerock Galaxy's and Dreadnought Galaxy's trashy planets, where they mark optimal places to throw Bob-ombs to destroy the trash in Bob-omb Blasting.
