Back At You! Trophy

You will encounter enemies known as a Hunter. These enemies attack by shooting red homing missiles at you. To earn this trophy, simply lure him into shooting a missile, and then quickly jumping back towards him so the missiles redirect at the Hunter. Do this successfully, and the missile will hit him, bubblizing the Hunter as a result and unlocking you the trophy. An easy level to do this is "Outta My Way" in Ticklish Temples.
