Petunia has always been full of adventure, and sometimes it would get her into trouble.

So, for the summer, her parents got her a foster puppy to teach Petunia how to be responsible. But it wasn't long before she realized her new foster pet, Pan was no ordinary puppy.

Petunia and Pan go on epic adventures while learning about depending on each other and how to be responsible, but most of all learning that growing up is not so bad after all.
