The listing, WordWorld: Shark's Loose Tooth (DVD, 2012) PBS Kids NICE has ended.
In SHARK'S FIRST LOOSE TOOTH, Shark enlists the help of the letter "P" to help him fall asleep so that the tooth fairy can come and collect his lost tooth, while A STRING IS THE THING! follows the WordFriends as they search for the right "ing" word to stop Frog's cake frosting machine from covering the entire WordWorld in frosting. DUCK PLAYS THE PIANO follows Bug, Bee and Fly as they continuously interrupt poor Duck's piano lesson, and Shark is apprehensive about going to school in SHARK'S FIRST DAY OF SCHOOL.
