Doctor Andonuts
Doctor Andonuts is a fictional character who appeared in Earthbound (Mother 2) for the Super Nintendo Entertainment System.
Doctor Andonuts is Jeff's father. When Jeff leaves Snowwood, his boarding school, and finds his father's lab, Doctor Andonuts reveals that he hasn't seen Jeff in 10 years. He doesn't seem to be a very good father figure to Jeff, but he does come through with some of his inventions. He also let's a docile caveman live in his laboratory later in the game.
Sky runner
The sky runner is a device that Doctor Andonuts made that Jeff uses to get to Threed to find Ness and Paula. It crash lands and is later fixed up so the gang can make their way to Summer's, where it is thrashed beyond repair.
Instant Revitalization Device
As the name implies, the IRD instantly revitalizes whomever uses it. In Earthbound it is the equivalant of staying a night at a hotel.
Phase Distorter
Doctor Andonuts's last inventuion in Earthbound. He works in conjunction with the Mr. Saturn population and Apple Kid, another inventor. (Though Apple Kid is a bit inexperienced, and his inventions tend to be off the wall) The Phase Distorter takes on the appearance of a Mr. Saturn and requires Xenonyte to operate. Ness and friends must have their souls transmitted into robotic bodies to use this invention, as it would kill their human bodies.
Once the Phase Distorter is used and Ness and friends arrive at their destination, it can be used to heal and to call Ness's father.
