In this giggle-inspiring romp, fellow artists Scribbles (a cat) and Ink (a mouse) go paw-to-paw in a special competition. They want to enter a "Draw a Dinosaur" contest so they can win the grand prize: two tickets to a mud-themed amusement park. Ink is secretly scared of drawing a dinosaur, however, and urges Scribbles to have a go at it. But Scribble's effort looks like a prehistoric chicken! When Ink draws, he makes an egg, and insists there's a dinosaur inside it. Strangely enough, he's right. The egg drawing hatches, a baby dino crawls out, and he starts wailing for his mommy. All at once, a Chick-a-saurus comes in and scoops the baby into her feathery arms. Cat and mouse know they won't win the contest now, so Ink creates a "Best Buddy" trophy for Scribbles, and together the cat, the mouse, and the just-drawn dino-duo throw a mud party of their own!
