Big the Cat is a laid-back kind of character. He cares about his friends and doesn't want to see them hurt, especially Froggy. He's also very kind and gentle, but he's also not the smartest guy in the group. For this story specifically, Big becomes an alien zombie after he touches sentient alien slime from a meteorite. As a zombie, he has a droning, monotone voice you'd hear in a typical zombie movie.

The only line for auditions where you have to act like a zombie is the second line, the remaining lines are normal Big lines you'd probably hear in a Sonic game or cartoon.
