Grizzy and The Lemmings IV (35)

Grizzy sets sail with his fishing gear. But he has no intention of fishing: it's a scheme to enjoy a jar of Yummy chocolate spread alone in peace. The Lemmings sense the subterfuge and sink his boat to get the treat, which sinks to the ocean depths. The characters dive in pursuit and discover a school of intelligent crabs that live in an underwater city. Their treasure is a substance that’s even yummier than Yummy.
