The Note is an item found in Putt-Putt Goes to the Moon.
This note is ejected out of the Moon City Gas's red machine when the machine is clicked. The note will tell Putt-Putt that if he needs rocket fuel, he will find Robbie Radar at the Moon Bubble Apartment (which room he is staying at varies). If Putt-Putt goes to the room at where Robbie Radar is said to be staying at and somebody else is there, that person will reveal that Robbie Radar left, but they will tell him which room he just went into and gives new note directions in case the player forgets. After Putt-Putt finds Robbie Radar and meets him back at the gas station, Putt-Putt will obtain the rocket fuel, which will replace the note.
