So he starts shoving a big mackerel in. That should be enough, right? But no! It falls in easier than expected. In fact, when he pulls out a salmon it all but falls inside.

Drulb stares at the bag, then at the demon, and back to the bag again. "This thing ain't so little as it looks, is it?"

And so he starts emptying the fish into it in earnest. He goes through one crate and starts with the next. "That thing's gonna eat all my stock!"
