What does a strange, long, made-up word sound like? Esmeralda came up with the perfect name for rosamond's pet concert. But she lost the pink Paper where she wrote the word-andd she can't remember what it is. Nate the great and his dog, Sludge, take on the unusual case, and they are soon braving pink papers and Barking, oinking, and talking pets. Will Nate and Sludge find the word in time for the show to go on?
