"I would normally agree with you, but just look at them? They're stuck in this super tacky shop," Ursula says and gestures to a nearby shelf displaying the world's ugliest googly-eyed seashell animals. "And, okay fine, they probably don't realize this, but they're ugly and no one is going to adopt them unless you do, Nia." By this point, it seems that Nia was correct and the hermit crabs have little interest in suddenly leaping at their faces and instead just wiggle their antennae a lot.

Still, it doesn't seem like a terrible idea to search 'can hermit crabs spit acid' on her phone, but Ursula gives up after the the fifth time of typing in 'herbit crbs'.

"I'm pretty sure they don't actually spit acid," she concludes aloud, as if anyone else was concerned about this.
