Gold Bowser Statue
From the Super Mario Wiki
Gold Bowser Statues are statues of Bowser that first appeared in Super Mario World. Instead of shooting fireballs they jump toward Mario or Luigi, and, unlike the gray statues, the gold ones can hurt the brothers by direct contact. The only way to defeat it is to lure it into a lava pit.
Their immobile counterparts are the Gray Bowser Statues.
