Super Rabbit Boy’s Team-Up Trouble!

An interesting layer between reader and story - the adventures of Super Rabbit Boy and Mole Girl are within a video game, and the players of the game (siblings Sunny and Rue) are sometimes seen playing the game, causing success or mishap in the game world.

The two players, and their avatars, must learn to work with one another and not let pride get in the way of having fun or vanquishing a common foe, represented here by the level bosses. The characters of the game are learning this in a story that would stand on its own, but they are simply mirroring the actions and emotion of the players, a representation of their growth.

I don't know if I've ever read a book intended for 1st-2nd graders at a moderately advanced reading levels that so easily introduces metatextual framing and author surrogates?
