How many more ways can Pharrell Williams repackage “Happy?” After a theatrically stunning performance at the 57th annual Grammys, Pharrell has now inked a deal to bring “Happy” into a kids book.

According to Billboard, the super producer has an agreement with Putnam Books for Young Readers for four picture books. Putnam announced that the book, “Happy,” will be published Sept. 22nd and will feature photographs of children from around the world “celebrating what it means to be happy.”

The initial publishing will print 250,000 copies.
