The shell pops off so you can squeeze the little turtle when you're stressed, then click it back on. I clipped mine to my ita bag and it survived a whole convention day without losing its shape.

The little shell pops off easily, which I didn't expect to enjoy as much as I do — good for fidgeting at my desk. The plush is soft enough to clip on my backpack without it feeling bulky. Wish the clip were a bit sturdier, but it's held up fine so far.

Cuter in photos than in hand, honestly — the plush is smaller than I expected and the detachable shell needs a firm tug to come off. It clips fine onto my backpack, though, and the turtle face is charming enough that I kept it.
