Meet Ophelia von Hairball the Fifth of Burglaria. She's snazzy, stealthy, and stylish—she's also the world's #1 cat burglar and an elite member of the Furry Feline Burglary Institute (FFBI). Ophelia loves the art of the heists... and she's an honorable thief and always gives back what she takes. Ophelia likes to work solo. So what's the fishy sidekick doing here?!
OSCAR F. GOLD
Ta-da! Introducing Oscar Fishgerald Gold, senior inventor extraordinaire. He's high-tech, hilarious, and never without an idea. Oscar's been assigned by the FFBI to Ophelia von Hairball V.

More than anything, Oscar wants to be a useful sidekick on daring, international heists!
