Say hello to Chester the Cheese, Sheldon the Shell, Theodore the Thermometer, and Whyatt the Whistle (I can't think of a name that starts with wh so i came up with that name.) Chester represents the ch sound. Sheldon represents the sh sound. Theodore represents the th sound. And Whyatt represents the wh sound.
Sorry if I used bitmap images for their bodies. So I wish someone like jdesnoyers should fix them or rename the wh character
