"Appeals to 4th-6th graders"-- back cover

Something fishy is going on! What happens when a talking fish, a runaway dog, and a herd of hog-like creatures descend on the woods behind Cody Brachman's house? An abosolute nightmare! His friend Sam wanted to stay inside and play video games all day, but Cody insisted they go wading in the creek. What starts as a fun morning in the water quickly turns into the scariest day the two friends have ever experienced. If Cody can't figure out why everything is going wrong, he's worried he won't live to swim another day!
