This page is all about the Truffle race on DBE:

Truffles lived in a modern civilzation on planet Plant and were killed by
the Saiyans who were un-willing to share their planet with the Truffles.
Along with the full moon, the Saiyans went Oozaru and wiped out the entire
race. After the destruction, Planet Plant was renamed Planet Vegeta (after the Saiyan king), and the Saiyans later on learned how to use the technology left behind. They can use their knowledge of machines to upgrade their body with Bio-Tech enhancements. Years after the Truffles were thought to be totally wiped out, a few truffles came forth and restarted the race of truffles on the northern end of planet Vegeta.

When Truffles block an attack with a shield, it will heal them depending on their shield block tier.
