When a bored Maya and Willy bust out of winter lock down early, they are catapulted headfirst into a top secret mission! Entrusted with the care of a sacred seed, Maya and Willy team up with their old pal's Arnie and Barney to deliver the seed to its new home atop the mysterious Bonsai Mountain. But when their seed hatches, Maya and Willy come face to face with their biggest responsibility yet - a squishy little princess called Smoosh! This adventure is a LOT more than they bargained for as they take on bounty hunters, thugs and ruthless enemies, to return the lost princess to her mountain colony, only to find it hanging in the balance of a turf war and remorseless predators. Willy discovers a side of himself that he never expected, as he becomes protective of the tiny princess, but to save her, and her colony, Maya must learn that trust is not just a word, it has to be earned!
