Gale's chest problem and the alteration of those tadpoles have actually kind of the same origin. As it's the same all-powerfull cosmological-rule-changing magic.
About the tadpoles crawling out, why shoud it have stay there? Noone were coming to save its host. Personally i'm more curious to know where it's going. And if it can infect people on its own.
