The 29-year-old captioned the summer video: "Hi from the #theprismaticworldtour."
Perry later posted another pic on Monday, thanking the waterpark. She wrote: "Thank you @schlitterbahn KC for hosting the kids on #theprismaticworldtour today! We can't wait to do our costume changes with our sunburns tomorrow!"
One thing's for sure, this "California Gurl" knows how to do summer right!
