"Clean It Up" is a song sung by Mr. Knox and Fox in Socks helped by The Cat in the Hat and The Little Cats as they clean up around the playhouse. As they clean up you really get to cheak out the whole house and it's really neat to see stuff you don't get to see while watching any of the other shows. It is featured on Episode 202: The Cat in the Hat Cleans Up His Act of The Wubbulous World of Dr. Seuss.
