HOLLYWOOD — Cartoons, comics, characters, repeat. Every nook of the Titmouse animation studio in Hollywood is filled with relics of pop-culture history and creations too obscure to name.

There are articulated action figures exploding off desks; plush loaves of bread stuffed into bookshelves; a smiling, shark-shaped guitar; and some equally friendly fungus-themed ornaments mounted like family portraits. With offices filled with artists in headphones, silently bobbing their heads; white boards crammed with inside jokes, sketches and work notes; and a 10-foot-tall sculpture of a guitar-toting Bigfoot in sunglasses guarding the parking lot, this is no average workplace, even by Hollywood standards.

The artifacts collected here may strike a chord if you watch late-night cartoons. The imprint of Chris Prynoski, president and owner of the company, is everywhere here. He and his wife, Shannon Prynoski, vice president and co-owner, moved here from New York and in 2000 founded Titmouse, a small start-up.

The firm grew to a full-service production company well known in the cartoon world, with three offices and more than 500 employees. Titmouse has 12 series in production, including pilots, films, commercials and web promos, and work that has appeared on Netflix, Adult Swim, Nickelodeon, Disney and others. It’s probably best known for the cult hits “Metalocalypse” and “The Venture Bros.” — and for its out-there founder, Mr. Prynoski, 46, with his trademark lumberjack beard, glasses and low-slung cap. You’ll find his lair past a pair of arcade-era consoles — Asteroids and Pacman — and around a sweeping hallway covered by a black-and-white Travis Millard mural of a doglike creature eerily reminiscent of Yoshitomo Nara’s “Your Dog” sculpture.
