Meet Pip: small paws, big plans, and a weakness for shiny things. In Teach the Thief, every heist starts with two choices. Pick two treasures that share a color, a shape, or both, then watch Pip scoop up everything that matches. The trick? Make every grab count—and leave the protected treasure alone. A LITTLE CHOICE. A BIG HAUL. Match different shapes of the same color to collect that color. Match the same shape in different colors to collect that shape. Match both to narrow the haul.
