Litterbot: Riff shares his dream of becoming an inventor with his friends. When Baby Bop's papers blow off the table and litter the park, Riff seizes the opportunity to show them his first invention. He invented something to pick up litter...the Litterbot! In the end, the robot malfunctions and creates even more trash. It's up to Barney and Baby Bop to teach Riff that they don't need a robot to clean up - they can clean up after themselves! Educational theme: Responsibility and environmental awareness.
