Just fill the fat little pen with water and brush — prehistoric giants roar to life in vivid color right before your child's eyes. Let the page dry and the color disappears, so every dino scene can be painted again and again with zero mess.

Four thick, wipe-clean pages are packed with T. rex, stegosaurus, triceratops and friends, plus hidden pictures to hunt down on every visit. No paint pots, no markers, no stained fingers — just tidy, screen-free fun that's ready the moment boredom strikes.

Slim and spill-proof, it slips into a diaper bag or backpack for instant entertainment at the table, in the car or on a plane.
