Book excerpt: Kids will love getting to know Plankton and Mussel in this laugh-out-loud, under-the-sea picture book! In this funny, underwater picture book, Plankton says hello to Mussel, but Mussel doesn't say anything back. Plankton tries everything to get quiet Mussel to talk. In fact, Plankton gets VERY pushy about it! Will Mussel ever open his mouth? Kids will relate to Plankton's frustration with Mussel, and they will be anxious to see what happens when Mussel finally does open his mouth... Geisel Award Honoree Jonathan Fenske delivers a laugh-out-loud ocean story, and this is the perfect follow-up to Barnacle is Bored.
