So, I had it in my head for a little while now that Catt and Flickie adopt a dragon who's a very hyper-active puppy at heart. He likes to play, and when he plays, he bites, chews and swallows things. So it's all out of affection. He's based on my cat Cookie who loves biting me, lol. Anyway, their dragon will swallow them often, and he'll let them out if they ask. He likes them in there, and despite the smells and the gooeyness, they're ok with it. The first time their dragon ate them, it was terrifying though, lol. Until they learned he's just playing.
