Trout
Neon Play-Doh balls make great salmon egg imitations, but you can also mold a pinch around a fresh mealworm to make it stand out in stained water.
Catfish
Cats will eat a hunk of Play-Doh mixed with garlic powder. Packing this mix around your sinker can also lure fish to traditional hook baits as the putty dissolves.
Flounder
Hook a minnow, then stick a ball of Play-Doh on the point, covering the barb. It keeps the livie from sliding off, and amps visual appeal.
