How do you get fuel for the space ship on astro knights in poptropica?

Get a gold coin and then go to the muesem! After that you go to the second floor and click a book! After that the guy in charge will give you a library slip! Go to the Royal Library and then after that you go to the Non Fiction area and find the shelf McM! Click the label and then a hidden staircase will appear. Go down and get the moldy cheese and click the switch! Dont forget that! After that you go into the maidens room and you set down the moldy cheese! The mouse will run after it and then you catch it! Go to the mill and go inside! Go as far as you can go and find the black haired girl! She will tell you a secret! After that go to the fountain and click cresent moon, jupiter, little star, then the big sun! You will get a key! After that you go to the two haystacks close to the windmill! Sepearte the two haystacks and release the mouse! A owl will come and then follow you! Unlock the door under the haystacks and then you will break through that dirt wall. Lean on it for a while and then it will break! After that you see that robot again and it will self destruct! Then the fuel stick will fly into the other room and you click the owl then click the stick, then yourself! The owl will retriever the stick which is you fuel! Hope this helps! :D
