Garden Glen was buzzing with excitement. It was time for the town's annual Butterbloom Fest! Everyone was ready for the most perfect day of the year.

Millie Fleur's day goes downhill from there. Even as she tries to make the best of things, her problems grow bigger and bigger. Will a little help from her friends be enough to turn this bad day around?
