Chadwick and the Garplegrungen

What is that awful green and purple gunk bubbling up in the normally blue waters of the Chesapeake Bay? Chadwick the Crab and his friends--quiet Orville Oyster, shy Belly Jeans the Flounder, Dr. Mallard (that old quack), stately Baron Von Heron, and others--call the unsightly stuff garplegrungen (it rhymes with dungeon). Although they don't know what the garplegrungen is, they decide to find out and get rid of it once and for all. This is no simple task for a small blue crab, but as readers of Chadwick the Crab series know, Chadwick is not one to give up easily. This is a delightful sequel to its very popular predecessor. Early reader-ages 5-8.
