Chris reads Elmo, Telly and Rosita the story of Rico, The Very Helpful Robot, and the pals decide to become robots to help Chris at Hooper's store. They call themselves the Help-O-Bots!

At first they're a big help, but they go faster and faster and end up making more of a mess for Chris to clean up. They tell Chris that they can also change into brooms and vacuums and feather dusters to become the greatest cleaning force in the universe, but begin arguing about how to clean. The mess is even worse!

Chris suggests they figure out what they are really good at and help people with that. They decide that they are really good at the alphabet. They become the Alphabetabots and help someone remember what letter comes after "G." Success!
