Mia Talerico has her Halloween costume all picked out in this new still from Good Luck Charlie.

In the upcoming episode “Blankie Go Bye-Bye,” Teddy (Bridgit Mendler) enlists PJ (Jason Dolley) and Gabe’s (Bradley Steven Perry) help to throw Amy and Bob a surprise anniversary dinner. When Charlie’s (Talerico) favorite blankie is misplaced, Teddy tries to track it down, and PJ gets locked out of the house with Charlie left inside.

Meanwhile, Gabe does his part to help with the surprise by taking Bob and Amy to a movie, but Amy gets stuck watching a movie she doesn’t want to watch.

“Blankie Go Bye-Bye” premieres Sunday, August 15 @ 8:30PM ET/PT on Disney Channel.
