Doc finds her old toy cell phone, Louie, in the toy box, and discovers that his volume control is stuck in the "loud" position, which makes games like "Hide and Seek" and "Telephone" a little tricky. Doc fixes the volume button, but Louie is so used to using his loud voice, he can't seem to make it quieter! So Doc and the other toys find a way to cure his Superlouditis. Kids (along with Louie) learn the difference between using "indoor" voices and "outdoor" voices in this Level Pre-1 reader.
