Tulip and Doug: Friends for (almost) ever

Tulip was famous in her neighbourhood for two reasons: 1. She was a fearless adventurer. 2. She went everywhere with a seriously strange sidekick - a potato, called Doug! Tulip and Doug are inseparable, until catastrophe strikes and Tulip loses her best spuddy buddy. She is inconsolable, until she makes a new friend. A boy. With a pet rock ... called Susan.
