These guys were inspired by Bonkers' slippers that were singing to him while he was in the shower. I had got the idea to give an "animated," alive pair to Avan for cuteness :3. So now, he has Skid and Slide. Skid's the more snarky one, hence his taunting, and Slide's the more sarcastic one. Both co-sign each other often, and team up. Avan often wears them at night, hence why he's in his pajamas here.
