with your force field, hit the ice cubes back at the monster-try to stay away from it until shield recharges; good luck! ^_^
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)
When your shield is on let the snowballs bounce and hit the helicopter 3 times.
at these coordinates X:73 Y:83
You get it from the ice knight on the ice planet.
There are no cubes on Astro Knights island. There are ice floes on the Ice Planet, that you jump across to avoid the robot fish.
Go ontop of the chains, then click the switch on the back of the dragon, then put the ice in the dragons mouth.
At the top of the ice mountain.
It doesn't matter which order as long as you complete all three planets (jungle, fire, and ice). Fire is the hardest of the three.
To draw the sword from the crystal stone, you must have defeated all three planets (jungle, ice, and fire) and have all three knights with you. (see the related questions)

You have to beat the other two planets as well (Jungle and Ice). When you have all three of the knights with you, go in search of the Giant Asteroid in the Asteroid Belt. It should be near X-11 Y-82.
You have to beat the other two planets (jungle and ice) before confronting the Binary Bard on his secret asteroid (X-11 Y-82). You will need all three space knights with you.
