There is a green fuel rod inside the robot invader in the dungeon. But you have to get into the cell the back way, through Mordred's underground lab.
In Mordred's hideaway, go outside as the owl leaves, and feed it the mouse. Go back inside and push against the left wall. It is dirt and will fall down. Go left and enter the cell. When the robot explodes, walk up to the bars, click on the owl (Merlin) and then click on the green rod. The owl will fly down and pick it up for you.
The entire sequence to that point is:
1. get the coin from the fountain
2. get the library slip from the museum
3. go to the library, press the shelf labeled Mc-M
4. enter the dungeon, get the cheese and flip the switch
5. get the message and mouse from the maid's room
6. go to the mill and see the girl who has the Cosmic Symbols
7. go to the fountain, click on saturn, moon, star and sun
8. go down and get the key
9. go to the field, separate the hay bales and use the key
10. go inside, then follow the owl outside again
11. feed the mouse to the owl
12. push on the thin dirt wall and go through the hole
13. the robot will explode, throwing the fuel rod through the bars
14. click on the owl, then on the fuel rod and he will get it for you
The hovercraft runs on manure.
You have to get the fuel rod
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.
i do not know what you are talking about
In Astro Knights Island on Poptropica, the fuel for the hovercraft can be found in the fuel canisters located next to the dock where you first arrive on the island. You need to collect the fuel canister and use it to power the hovercraft to cross the toxic swamp.
Feed it the mechanical mouse (from the Maid's room) and the owl will follow you.
put the manure that i dude gives you in it.
get the fuel and put it in the rocket ship and put in 56 and 52.
you get mordred's bird and send him in the place that goes to the dungeon
The fuel rod powers the saucer Excalibur. The hovercraft runs on manure.
