Guardian Gloves
In Planet Horizon, after the area where you defeat Ashtarth, go down the stairs. Get the bomb throw, and go to the door in the "Up" area (not the one you came from). Get the Remote Control (bomb the statue and collect it) and step on the two buttons. Go back. Enter the door on the right. Move right, then put the statues on the buttons as was done during the first time in Planet Horizon. Wind bomb to the elevator platform. Throw a bomb downwards and press Z at the top of its arc. It should take away a small pillar object. Return to the beginning of the room. Go up the stairs. Wind bomb yourself across. In the next room, lightning bomb the platform and grab the part to get the Guardian Gloves.
