Yardrats

From Dragon Ball - Wiki on Neoseeker

Goku met the Yardrat race when his Saiyan space pod crashed into their planet during his escape from Planet Namek, following Frieza’s defeat. The Yardrats are a short, pink-skinned and peaceful people who nursed Goku back to health.

The common technique known by the Yardrat race is the Instant Transmission ability that allows a person to instantly appear at whichever location they concentrate on that has a ki source. They taught this technique to Goku and even gave him an outfit worn by all the members of their people.
