Insight Kids — an imprint of Insight Editions, a company that creates books for fandoms of all ages — is teaming up with MGA Entertainment‘s L.O.L. Surprise! for an Officially Blinged-Out series of interactive books and products launching on Sept. 1.

The series will debut in North America with four titles:

The L.O.L. Surprise! Book of Surprises ($14.99) includes a magic mirror decoder that kids can use to reveal secret messages and uncover details on their favorite L.O.L. Surprise! characters. The book features more than 100 surprises, including hidden pictures, secret stories, and doll-sized mini-books.

The L.O.L. Surprise! Photo Studio ($12.99) unfolds to reveal four Instagram-ready 3D scenes from the world of L.O.L. Surprise! Kids can pose L.O.L. Surprise! dolls or the three included paper dolls in scenes and lift the flaps to find hidden surprises.
