Maria helps Elmo write a story about the letter "G." Elmo is having trouble thinking of letter "G" words, but Maria reminds him of the letter "G" sound. Elmo thinks of the word "golf". He draws a picture of himself playing miniature golf and hitting the ball so hard it flies into space and lands on Planet "G!" Elmo remembers another "G" word, "goldfish", just like Dorothy, his pet fish! He draws a picture of himself riding on a goldfish up to the planet "G" to look for the golf ball.
He tries to think of another "G" word when Baby Bear stops by before he leaves for school. Baby Bear loves his teacher, Mother Goose. "Goose" begins with the letter "G!" Elmo incorporates a picture of a goose into his story. But uh-oh! The goose perches herself on Elmo's golf ball, thinking it's an egg. Elmo has to get the goose off the ball, but how will he do it? With the help of Zoe and her two friends who are "girls", Elmo sings the "Get up and Go Dance" song. He draws a picture of the goose getting up and dancing with the two girls as he leaves the golf ball behind.
All of a sudden, Elmo finds a hungry "goat" munching on a page of his story. When the goat stops eating, Elmo draws a picture of the goat trying to eat his golf ball in space. Luckily, in the story Elmo offers the goat some "goulash" and the goat drops the golf ball. He draws a picture of himself flying back to Sesame Street. Elmo excitedly reads the entire story of Elmo's Adventure on the Planet G to Maria and Chris.
