On the Ice Planet, you fight the Tigercopter.
Talk to Sir Gawain and he'll give you the Force Shield. When the copter drops round snowballs, bounce them back at him, aiming for the yellow lights. Each time he's hit, he'll crash and shoot at you. Jump. After three hits, he's defeated.
If your shield gets depleted, Dodge the ice missiles until it recharges.
Wait until it goes flat, then QUICKLY jump on it and go on. :D
Go behind the monster, climb on its back, pull the switch, then go in front of the monster and shoot the ice arrow into its mouth. Do this 3 times and you will defeat the monster.(see the related solution)

Once you reach the Pewter Moon and build a new ship, you fly to the three planets in search of the Princess. On each planet, you have to defeat the boss robotic monster and enlist the help of the three Astro Knights who have arrived on the planets. (see related question)
