There is no way to open the gate. If I remember correctly, you click on the robot and it self-destructs. Then, when the green cylinder-shaped power cell falls on the ground after the robot blows up, click on Merlin the owl, who should be flying beside you if you've found him already, then click on the power cell. Merlin can fit through the gate so he will fetch the power cell for you.
you fight the robot on jungle planet
One of the robot attackers was captured and put in the castle dungeon.
There is no jail on Astro Knights Island. There is a castle dungeon, where an attacking alien robot is being held after his capture. (see the related question)
Throw the switch when you get the cheese. You can enter the dungeon from Mordred's underground laboratory once you have the robot owl. (see the related question)
There doesn't seem to be a drain there. There's a robot owl, who will follow you if you feed him a mouse. There's a dirt wall you can push through, and a tunnel to the dungeon where the robot attacker is kept. The gate at the end is opened from the library entrance to the dungeon.
Still in the dungeon. Either the hole is too small, or he doesn't like dirt caves.
ohh u dont. well when u get to the other side of the dungeon cell, he self destructs. then u get the fuel rod he spits out by using the owl. ur welcome. DoNt WoRrY.. bE hApPy!!
The mechanicial owl has to get the fuel in the dungeon after the robot blows up.
Actually, Merlin has little to do on Astro Knights Island. He recovers the fuel rod from the dungeon when the robot self-destructs. And he battles Mordred at the very end of the island.
Feed the robot mouse to the owl, and then he will follow you. In the dungeon cell, click the owl, then the fuel rod, and he will retrieve it for you. (see related question)
On Astro Knights Island, the part of the quest that occurs on the planet Poptropica is in the kingdom of Arturus. The kingdom was attacked by robot invaders who have kidnapped the Princess.
Find the old cheese. . Give the cheese to the mouse and give the mouse to the owl.
