We will be showing a different episode of WorldWorld here each week! In Shark’s First Day of School, it’s the first day of school for Shark, but he is afraid to go. With the help of his friend Duck, and some encouragement from their teacher Cat, Shark’s fear turns to confidence, and by day’s end he’s at the head of the class. In Shark’s Loose Tooth, Shark looses his first baby tooth at a sleepover party with Duck. Shark needs to get to sleep fast so the tooth fairy can come and leave him a present, but he can’t fall asleep. With the help of his friend Duck and the letter P, Shark finds the word he needs to help him fall asleep.
