Puffskis

Puffskis (singular: Puffski) are, in the simplest sense, world-hopping puffballs. Their bodies are round and fuzzy, with nubby heads; however, they have arms and legs that they can retract into their body and pop out when needed. So you have some that scoot and some that walk according to personal preference.
Puffskis travel the multiverse for all kinds of reasons. Some just want a change of pace, others are looking for adventure, others think they have a message of love to spread from their mother goddess. They prefer worlds that are peaceful, abundant, and populated with interesting people. Mixolys is considered a good spot for a puff to visit due to the sheer variety of experiences to be had, though curiously, there aren't many actual set-up puff villages spotted around Mixolys. It's more like a spot for families that don't mind hustle and bustle and adventure seekers than a place for villages.
