The Mechana-Beaver has stopped recycling and the Animal Mechanicals have to find out the problem before Trash Masher Island fills up with junk! Unicorn finds the Beaver by flying high in the sky. The rest of the team use an old ladder to fix the track the junk trolleys travel on to deliver trash to the Beaver, but then they learn the Beaver's tail is worn out and can't work. The Animal Mechanicals recycle old things into a new tail and the Beaver gets back to work.
