Simply utilize Charged Tornado in back of the statue with green eyes. While Ripto charges the attack to deflect it back at you, run behind the statue. Ripto will be destroyed. With the blue one, charge up the Ice Breath. Go behind it and attack Ripto. When destroying the red eyed one, charge up the Flame Breath. Go beside the statue, attack, and run behind the statue. Ripto will destroy that statue.
