I thought it would be cute if they all got pets once they get to Earth! So:
Fluorite has a tortoise. They're very slow, kind, and wise. They're also big enough to fend off external attacks. Just like her.
Rhodonite has a fish. Originally I was going to give her a service dog for her anxiety, but watching a creature with a delicate frill calmly float around is good for her mental health.
The Twins of Rutile have a cat. A Siamese cat. I hope I don't have to explain why.
And Padoparadscha has a sloth, the only pet that reacts at her pace!
