The Maw is arguably the biggest fish in Cat Goes Fishing.The massive Maw lurks in the dark depth,feeding on the bulbfish,that thrive there. The Maw is only catchable if you hook the Bulbfish that is in its mouth. The Maw will then bite the hook. It actually shares its name with a location in Little Nightmares. Its body is mainly grey, his fins are a darker grey than the body, and it has lighter grey spots on his underbelly, as seen in the picture.
The Maw is the 4th most expensive Huge fish in the game, standing at $140,000, and basically beating the Noctis and the Moga by $20,000, but still topped by the Hamahed, Swordfish, and Cave Shark.
