Plantian

Plantians are pink skinned oval shaped headed species from planet Vegeta in the past. It is unknown what happened to them by the time the Tuffle and later the Saiyans arrived to the planet.

Plantians are usually no harm to others as seen in the Episode of Bardock. One Plantian healed Bardock using a special potion similar to what the Planet Trade Organization uses to treat their soldiers.
