The Boonboomger collaborates with popular YouTuber HIKAKIN on a shoot at a racing circuit that Taiya purchased. But when Princess Nicola Keydoor of planet Trickle who escaped from her home planet to Earth suddenly appeared, the Boonboomgers are now involved in a major incident that shakes the peace of planet Earth! This is Boonboomger's biggest mission yet!
