Scribbles the cat and Ink the mouse are buddies and fellow artists. Ink is excited for them to enter a "Draw a Dinosaur" contest. The prize is two tickets to a mud-themed amusement park. Ink is secretly scared of drawing a dinosaur. He urges Scribbles to have a go at it but thinks the resulting effort looks like a prehistoric chicken. Next, Ink draws...an egg and insists there's a dinosaur inside it. He's right! As the egg-drawing hatches, a baby dino crawls out, and starts wailing for his mommy. Suddenly, the Chick-a-saurus comes in and scoops the baby into her feathery arms. Realizing that they won't win the contest, Ink creates a "Best Buddy" trophy for Scribbles and Ink and dino-duo throw a mud party for Ink!
