Booboo Stewart on 'Good Luck Charlie' -- FIRST LOOK!

Booboo Stewart helps Bridgit Mendler out during a surf lesson in this exclusive new still from Good Luck Charlie.

In the upcoming episode, “Sun Show, Part 1″ – It’s Bob (Eric Allan Kramer) and Amy’s (Leigh-Allyn Baker) 20th wedding anniversary, and to everyone’s surprise, the usually stingy Bob surprises the entire family with a trip to Hawaii — but there are some kickers.

Upon arrival, Teddy (Mendler) wants to get surfing lessons from the cute instructor Kai (Stewart), and PJ (Jason Dolley) and Gabe (Bradley Steven Perry) go on a helicopter ride with a scarily unpredictable pilot.

JJJ was on set with Booboo and Bridgit and got the scoop on what’s happening. Check out a bit of our exclusive interview below and stay tuned for more!

“Sun Show, Part I” premieres THIS Sunday, July 24th @ 8:30M ET/PT on Disney Channel.
