You can't fix or refill the broken fuel rod. Fortunately, there is a replacement that is powering the imprisoned robot invader. Go back to the dungeon through Mordred's secret laboratory, and you can get the replacement rod with the help of the robot owl Merlin.
(see related question)
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.
The hovercraft runs on manure.
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.
