Ferrets from Planet Ferretonia!

Meems and Feefs are ferrets from the planet Ferretonia. When they secretly carry out an experiment using Ferretonia's forbidden Ancient Tech, it all goes wrong, and they end up crash-landing on Earth!

Meems is a smart, cheeky, and tech-savvy ferret from the planet Ferretonia. Feefs is his goofy, happy-go-lucky brother. Unsatisfied and bored with their quiet life on Ferretonia, the brothers build a forbidden Travel Opal to go on adventure but accidentally bite off more than they can chew and get stuck on planet Earth with no way to get home. The ferrets journey to an animal shelter where they meet a shy teen named Liza. After using a Communication Opal on Liza to transcend language barriers, Meems and Feefs put their trust in her and embark on a race-against-time adventure, or else they're doomed to stay on Earth forever!
