Elmo Says Achoo! is a 2000 Sesame Street "Step Into Reading" book featuring Elmo. In the book, Elmo sneezes as he carries a present through Sesame Street, upsetting everything as he goes by -- knocking down a wall, and scattering people left and right with his mighty blows. It turns out that he's carrying a new stinkweed plant to Oscar the Grouch.
