You have to go down into mordrid's lab with the owl. You climb through the secret passageway, and find yourself in the castle's dungeons. The alien self destructs, but leaves a green fuel rod. you switch this rod with the one in the flying saucer
The Pewter MoonThe coordinates X-56 Y-52 are from the page under Mordred's bed. The Pewter Moon (orbiting planet Poptropica) is the only place the saucer has the fuel to reach. You cannot get to the three planets in the saucer. You can dial the coordinates in when you have replaced the broken green Fuel Rod.
No oil on Astro Knights Island. The hovercraft runs on manure, and the crashed saucer Excalibur needs a replacement for its broken green fuel rod. (see the related question)
When you get a new fuel rod, just place it in the spot on the saucer and it will lock in. (see related question)
x-56 y-52 it will get you to the moon. the moon is the only place you can go on the flying saucer
There is more than one vial (not called that) on Poptropica islands:Astro Knights IslandGet the replacement green fuel rod from the robot invader in the dungeon and replace the damaged one in the saucer Excalibur. Get the list of planets from the Queen, but set the saucer dials to X-56 Y-52 (the Pewter Moon).Steamworks IslandThe vial (beaker) from the Museum will be used to mix a herbicide in the lab (production zone) on the far side of the drawbridge.
The "broken pipe" refers to the damaged fuel cell in the saucer Excalibur, which is crashed in the mud swamp past the Mill. To reach the saucer, use the hovercraft. To fly the saucer, get a replacement green fuel cell. (see related questions)
Fix the saucer, beat the three planets, and defeat the Binary Bard.
