The Captive Invader Robot
When you get the cheese, pull the switch. This opens the back gate to the dungeon. When you have fed the mouse to the robot owl, push down the dirt wall in the tunnel from Mordred's lab to the dungeon. The robot explodes. Click Merlin then the fuel rod and he will fly through the bars to retrieve it.
The Giant Robot Battle Suit
First (as the owl) you have to pick up the bombs -- when they are flashing red you drop them on the robot. You do this twice. Then when you are your Poptropican, climb up the robot to reach the platform, then jump to one of the hanging chandeliers. Make sure the robot is under you when it shoots the laser at the chandelier, which falls on it. Repeat the process by jumping to the chandelier on the other side and the robot is destroyed.
There are robot creatures on Astro Knights island, and you use the Mystical Weapons of Arturus to defeat them on the three planets.
Nothing. When you defeat the giant robot, you take the Orb back to Arturus and Mordred is left behind in his castle. You receive the island medallion.
all you get is the island medallion and 100 credits
