kill the alien in the castle and get Merlin (the owl) to get the tube
A person can get the ship to work on Astro Nights by obtaining the green rod from the alien. A bag of manure will also work to fuel the ship.
To get the green tube in Poptropica's Astro Knights Island, you need to visit the castle courtyard and find the robot seahorse in the fountain. Ride the seahorse up to the top of the fountain to retrieve the green tube.
I have no clue I was trying to figure that out to. Astro Nights was one of the only islands I have not beat. But I think you use the robot mouse or owl.
you go into the windmill there will be a glow stick on top of a box.
At the very bottom of the jungle (you have to fall) in the middle.
you click on the owl then cklick on the green tube and the owl will bring it
