This is a list of all inventions that are made by Dr. Andonuts in the Mother series.
In EarthBound
Instant Revitalizing Device
A pod which, in only a few seconds, fully revitalizes its user, just like a good night's sleep.
Phase Distorter
Andonuts' last invention during the events of EarthBound. He works in conjunction with the Mr. Saturn population and Apple Kid, a youth inventor from Twoson. The first Phase Distorter is stolen by Pokey Minch before Ness and friends have a chance to use it. Dr. Andonuts and the gang have to construct another Phase Distorter, called the Phase Distorter 2.0. The Phase Distorter 2.0 takes on the appearance of a Mr. Saturn and requires Zexonyte to operate. Ness and friends must have their souls transmitted into robotic bodies to use this invention, as it would destroy their human bodies. Once the Phase Distorter is used and Ness and friends arrive at their destination, it can be used to repair the robot bodies and to call Ness' father.
Sky Runner
A UFO-styled aircraft. Dr. Andonuts' son Jeff uses it to travel to Threed to rescue Ness and Paula Polestar. The Sky Runner crashes, but is later fixed up so the gang can make their way to Summers. However, it crashes again, and while Ness and his friends are unhurt, only a few chunks of debris are what remain of it.
In Mother 3
Absolutely Safe Capsule
Built with the specifications that once sealed, it cannot be opened again by anyone, including any person inside of it, this device indeed keeps its contents "absolutely safe." Pokey Minch uses the Absolutely Safe Capsule as a last resort in the final battle of Mother 3, before realizing that he has become trapped in the machine forever, doomed to eventually die in complete isolation.
Ultimate Chimera
Created in the Chimera Labs to be the ultimate killing machine, it went rouge before Andonuts could destroy its last weakness, an off-button on its back. However, the bird on its back could simply press the button again to revive it.
