I'm not sure whats happening but I quit and restarted my game and it was still happening. Lagjisuibin (my second Mochi) specifically seems to be getting pushed by something and keeps sliding. I switched to Peibunbun and Raidura on desktop and the bug isn't happening to them. Very strange...Its happening on desktop mode and island mode (first two videos). Not sure if the minipet is also related (3rd video provided, Lagjisuibin's hat is also taken off but going back to customization fixed it) as it went away after going to desktop/quitting game, but I'll include a video of it too. It seems the minipet is rapidly flying in the air offscreen and casting a shadow.
I'll just keep Peibunbun as my desktop pet for now since its a bit distracting

Can that even happen...?
