Telepathy is a PSI power in Mother and EarthBound. Learned by Ninten and Ana, it allows them to read the minds of certain people or animals. Ness and Paula are able to use this skill; however, while Ness displays an ability to speak to and understand animals, Paula shows a much greater ability, using it to contact Ness and Jeff when she is in trouble. Telepathy in EarthBound is passive and cannot be controlled by the player. It is also used to enter the world of Magicant in Mother with the use of the GGF's Diary and a pink shell.
In Mother I, the players starts out with the power (without anyone explaining it's purpose or functioning) and is first required to use it on an odd stone inside a cave west of Podunk. Other purposes include using the magical fountain at Magicant as an ATM and solving the riddle one of the Magicant's Palace guards sets on Ninten.
