Walmart offers the Zoomer Chomplingz Dinosaur Chance for $19.83. Opt for in-store pickup to avoid the $4.97 shipping charge. That's $5 under our December mention of one of its friends and the best price we've seen for any Chomplingz dinosaur. (It's a current low by $8.) This robo-dinosaur features mouth and nose sensors, interactive games, guard mode, chip accessory, and requires three AAA batteries (not included).
