Cuddles
Acting as Head of Security, you can frequently find Cuddles asleep on an office chair, begging for food during lunch-time or chasing his ball across the office. Contrary to his name, he hates to cuddle and values his personal space. He’s an avid apple-eater and enjoys chasing chipmunks in his spare time. Cuddles failed to graduate from Doggie Daycare (due to his tendency to herd his peers) but that didn't stop him from pursuing his dreams of providing top notch security services.
