Audio problem: At the beginning, when Professor Broom and the young Hellboy are spending Christmas Eve at a military base in New Mexico, Broom insists that Hellboy go to bed, while Hellboy insists that Broom first tell a bedtime story: "Just one, and then I'll go to bed right away, I promise!" Which is an overdub (one of several in this scene). More than once, the young Hellboy's mouth visibly says something very different than is heard in the audio.

Other mistake: When one of the agents is ambushed by the Tooth Fairies he is reduced to a skeleton, with his teeth still visible. However, it was earlier stated that Tooth Fairies start by eating the teeth, then finish off the rest of a body.

Chosen answer: Why not wear it? It's clearly something that's useful to him, even if it's apparently not particularly essential. It may simply just make him more comfortable, like a human wearing a scarf in cold weather - allowing him to breathe the water that he prefers rather than air. There's never any mention that Abe can only survive for a limited time out of the water; equally, there's no suggestion that he's particularly vulnerable to atmospheric microbes. It's part of his equipment that he uses when he wishes to, that's all.
