Either freeze the Geruta and turn off and on Ice to quickly thaw it and save Energy, or carefully jump over it without freezing it or getting hit. Then lure it left by jumping towards it from below with a series of mid-air SpringBall jumps. Freeze it when it performs a larger swoop and use it as a platform to get to the item. Be careful not to jump into the Geruta's path to avoid hitting it.
