The Maw is arguably one of the biggest fish in Cat Goes Fishing. The massive Maw lurks in the dark depths, feeding on the Bulbfish that thrive there. The Maw is only catchable if you EITHER hook the Bulbfish (You need a huge hook) that is in its mouth, or hooking a Bulbfish that is not in its mouth and getting the hook near it (You also need a huge hook). ONLY then will the Maw bite your hook.A strategy involves luring the Maw near the surface, then letting it bite, so you don't have too fight it which is useful for Realistic Mode. 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 $450,000, and basically beating the Noctis by $200,000, and the Moga by 270,000 but still topped by the Cave Shark, Abyssal, and Dragon.
It shares its name with a location in Little Nightmares.
