Hermit crab within a shell?

I’ve seen that a few times, normally the snail will give up on the hermit crab shell or the hermit crab will change shells if it gets annoyed enough (make sure to have similar shells in the tank near it). Normally you don’t have to pull the snail off unless it's completely blocking the hermit crab from moving/entering/exiting it's own shell.

What ended up happening, OP?
