The space mice are in training for their next encounter with Haggar's blue cat. Pidge gets the idea to even build them their own version of a Voltron Lion. Haggar brings to Arus her newest Ro-Beast, which creates a canyon in the ground. The Voltron Force can't see it, because its hiding in the canyon walls. Suddenly, the Ro-Beast shoots out chains from both sides and captures Voltron. Now it is up to the mice to try and help Voltron save the day.
