In The Totally Ninja Raccoons and The Secret of Nessmuk Lake, the Ninja Raccoons continue their ninja training, learn to respect privacy, and meet a creature of Scottish legend, The Loch Ness Monster!

The Cat Board plots against the Ninja Raccons as the Raccoons explore the depths of Lake Nessmuk. Will the Raccoons learn the secret? Will the Cat Board triumph? Will Rascal finally learn to swim?

There are more things in heaven and earth than these three brothers ever dreamed. Cats are trying to take over the world; monsters are real; and Chinese food really will make you hungry soon after you eat it. It's up to the Ninja Raccoons to do something about it.
