Many people are stuck in the part that you have to get the UFO out of the mud well heres how:
To get the fuel you must get the gold coin out of the fountain and then you clickk the planets in order that get out and go into the doungon thats under the hay there will be an owl down there he will fly out then you have to follow him out. once you are out release the robo mouse. The owl will go after it and eat it but then he will follow you back into the doungon. go to the very back and push the wall till it breaks then keep going untill you are at the back of the dungon go in to the small empty space then there will be a robot that will say "Intuder self destuct in 3 2 1" then he wiill explod and his fuel will fall throught the bars andyou need to send the the owl throught to get it. then go back to the UFO an put in the fuel and punch in the coordinates 56 52 it will fly you to the moon!
Hope this helped if you have any questions just post a comment or send me a personal message! 8)
