Melissa & Doug On the Go Secret Decoder - Slippery Flippers

Puzzles with a hidden twist — and a decoder tool that cracks them open. This On the Go activity pad packs pages of ocean-themed "Slippery Flippers" riddles, mazes, and mysteries whose answers stay invisible until kids sweep the special reveal tool across the page.

The reveal-and-discover format keeps young detectives hooked, quietly sharpening reading, logic, and problem-solving. Compact and self-contained, it's the perfect boredom-beater for the car, the plane, or a restaurant wait — with no loose pieces to lose.

Secret-agent fun that fits right in a backpack.
