Chell mostly spends his time out fishing at the shore and gathering clams, or working (albeit not terribly quickly) at cutting thorns off of the barrier's hedge, so he can remove a branch or two at a time from it, to try drying it out for use in... something. First order of business is to have wood for use, before truly committing to using it for anything, after all.

Also possible: he'll be cooking it up, for those that need to eat (as he does not). He's not a great cook at all, but he's learning. If you know better how to cook fish than he does (he's still pretty new to it, but he can take direction!) he'd welcome the help.
