Molly and Bill crouched behind a rhododendron, peering through the window at a living room packed with screaming children, a lopsided piƱata, and a mountain of glittering presents. "Forty gifts," Molly whispered. "All in gold foil. I count three PlayStations." "Or socks," Bill said. "Socks never come in gold foil. Phase one: we wait for the cake. Phase two: the kids swarm the sugar, and we break in and steal every present." "What about the clown?" "He's on break." "Clowns never take breaks." "Then we bribe him with a balloon sword." Bill nodded solemnly, as though this were the most sensible plan in the world. He tugged at his bunny ears, which were far too small and kept snapping back into his face like a rubber band with a grudge. "Nobody suspects a rabbit." "Everybody suspects a six-foot rabbit." "Getaway vehicle?" "Grandma's mobility scooter." "Top speed is four miles an hour." "Nobody chases a grandma, Bill." A sudden shriek erupted from the house. Bill flinched, stepped in a sprinkler, and squeaked. "Shh!" Molly hissed. "Stealth, Bill." "I'm the stealthiest rabbit alive." "You're the squeakiest rabbit alive." Bill grinned and tiptoed toward the back door, squeaking with every step. "Born ready."
