A tiny prince falls through a broken rainbow, and suddenly the whole problem becomes saving something beautiful just because it matters. The Ham-Hams don't overthink it, they just start moving, treating a kid's adventure like it's the most important thing in the world. That earnestness, that willingness to care completely about something small and impossible, is what makes this feel like Saturday morning the way nothing else does anymore.
When the rainbow vanishes from the sky, a prince named Bo tumbles down with it and lands among the Ham-Hams. Hamtaro and his hamster friends take it upon themselves to help Bo get the rainbow back. Adapted from one of the Hamtaro video games, this single-episode OVA is a light fantasy adventure with plenty of comedy, built around the Ham-Hams teaming up to put a missing rainbow back where it belongs.
