Belly Button Tales

When Hailie and Madi ask their mom for a bedtime story, they aren't expecting THIS story..."Madi! Help! I'm falling into my belly button!"Inside Hailie's belly button, they hear growling, and look like the perfect snack for the big, hungry snake-beast living in Hailie's tummy. Unless they want to become monster food, they need to escape. Fast. Will Madi and Hailie escape, or will they be trapped inside Hailie's belly button forever?
