Yeah. These are actually lithium rechargeable too. There is a molded housing and built in servo with like 20% range on a small arm that goes in the tail. I haven't taken one apart but it is triggered off of impact like I would expect from a spring tilt/impact switch, though it could be some kind of MEMS chip.

Yeah we have one that does exactly that. Unfortunately our dog thinks it's his toy.

Dogs are dumb.

Of course it’s not his toy! All toys are belong to Cat! (Including Dog.)

The good news is that he's really careful with his toys. It's rare that he destroys one, and even then it's more from wear and tear, not outright shredding it like many dogs. So the fish might still work!
