Head to Toe! is a 2006 Sesame Street Play-A-Sound book which follows Elmo and his friends as they move and dance. 12 buttons provide sounds and character voices to accompany the story. There is also a game area at the bottom of the button panel, which can be used with an included game board and game pieces. The book was reissued in 2009 as Head to Toe! Go! Go! Go!, with additional material written by Jennifer H. Keast and illustrated by Tom Brannon. It was reissued again in 2010, without the "Happy Healthy Monsters" logo, as Head to Toe! Ready, Set, Go!
