I Have to Go is a 1990 Sesame Street storybook featuring Grover as a toddler.

Overall-clad Little Grover suddenly abandons his ride on a toy train and hurries outside, turning down invitations from his toddler friends to join them in play. He tells each friend he has to go, leaving them wondering what he means. He finds his Mommy gardening and informs her he has to go, and she understands that he needs to use the potty. Grover's Mommy helps him and reinforces her pride in him.
