Beanie In The Bottle - Beanie Books, #1

When Ben left school with his twin sister Beth, he thought it would be the same as any other day. This normally means sitting by Angie, the girl he is sweet on, and enjoying their short time together. However, Ben soon realized that this day would be different when an unexpected friend named Gloppy joins him in his seat. Gloppy made some poor choices on the bus that led to Ben's bus privileges getting revoked.
Ben would have to walk all the way to school. So, the next day, Ben recruited his friend Cole to take the shortcut through the haunted woods. On the way there, they broke some bottles, saw an outhouse with dead flies, and found an antique bottle that may or may not have something unexpected inside. All that happened next was the weirdest day EVER!
