MisterJaw dives on some fish for dinner, but he ends up swallowing a big rock. He tries to catch two pelicans, but they escape. His pal Catfish suggests that he go after a halibut. After all, they are easy targets... but not for MisterJaw, who gets a hankering to eat Harry Halibut. With Catfish's help, MisterJaw comes up with some very imaginative ways to capture his prey!
