When Corey , kin , and kon turn laney into a little girl and find out here biggest secret or their biggest fear ?

Dipper and Mabel are staying with some family friends while Stan is out of town on 'business'. Who knew it could be the best three weeks of their lives?

Leah Baxter is a girl who lives in Peaceville. She's on the guitar and does vocals for her band, The Sireans. But, at the most important competition they've ever been too, they meet a certain blue-haired, orange beanie wearing kid. Otherwise known as Corey Riffin. The Sireans and Grojband, as they're called, become good friends. Now, Leah has to deal with all kinds of drama coming into her life. Love, beatings, competitions, moving away... she needs some help. I do not own Grojband or it's characters. I do own Terrance, Kyle, Derek, Leah (Dyna), Chris, Joel, Dawn, Victoria, Claire, Jenna, Marianna and Chiara.

Corey & Laney are turned into 6 year olds due to Kin's faulty machine. At the same time a guy name Chuck set his eyes on stealing Laney, no matter her age.
