Flared shell opening on garden snail

[pyropyrope]

Hey so this is my big boy Garry and recently he has developed this weird flare around his mantle and the mantle protrudes a bit from his shell, and he has been rasping at the flare (we in this video imgur.com/gallery/wFlbYCi ). This all started after a recent fall that flaked some of the shell around the mantle and I’m wondering if that caused this, if it’s a problem, and if there’s anything I can do about it. imgur.com/gallery/JPvTtBD

Hello! This looks normal to me. Possibly where the part of his shell flaked off may just be bothering him. I would just keep a close eye on him for any suspicious behavior! I hope this helps!
