Moon City Gas is one of the locations in Putt-Putt Goes to the Moon.
Putt-Putt will need to go here in order to get rocket fuel. Once Putt-Putt enters the gas station, the player will need to click on the red machine (shown in picture on right), in order for it to spit a note out. Putt-Putt will learn from the note that in order to get rocket fuel, he will need to find Robbie Radar at the Moon Bubble Apartments (what room and floor he is in varies between games). After Putt-Putt finds Robbie, both characters will automatically return to the gas station, where Robbie will give Putt-Putt the rocket fuel he requested.
