is he ok??

mo normally sleeps out in the enclosure and has been eating well but the last 2 days he’s been climbing up the side of his enclosure. he has a bridge in his enclosure and he’s done this once before but i don’t know if he’s just a weirdo who likes to climb the walls or something might be bothering him. i don’t know why but im just stressed that somethings wrong but i don’t know what would be wrong should i try to give him more and better climbing areas?
