While celebrating the three-year anniversary of Hal and his favorite chew toy, Mr. Chewinsky, Nature Cat accidentally drops Mr. Chewinsky down a storm drain. The gang tracks Mr. Chewinsky through the sewer system, into a river, and out to the ocean. Oh, no! Can they rescue Mr. Chewinsky or will he become ocean litter? Thankfully, the ocean connects the pals to nature explorers from across the globe!
