The group performs a new song called 'The ABCs of Moving You' and it'll be stuck in your head for days!
"The two best childhood shows have once again made an amazing crossover. They definitely need to make an entire DVD and album together," said one excited fan.
"Now I know what my daughter will want to listen to a million times this week," added another.
