Piff is a bit of a dork and gets moved to tears easily. His mood can change quickly, sad one moment and bouncing around singing the next. He's easily excited and puts his passion into everything he does. Sometimes it's a little too much passion for his own good. Despite all this, he's also very mature and understands the world around him. He may hide it sometimes by trying his best to stay positive, but he knows things are far from perfect.
Piff used to spend a lot of his life alone, finding himself at the wrong end of things and being hurt or abandoned by others. It wasn't until he met his friends Bon-bon and later Igneous that he would see he wasn't alone to these pains and then grow more strength to withstand it. Because of them, he does what he can to reach out to others in need, even if he can't always help much.
Piff is sweet, and loves a lot of sweet things - especially honey. Sometimes he can be found with a small piece of honeycomb in his mouth, chewing it or licking away at it.
