[8] After attending law school, Schwarz realized that he wanted more playfulness in his career causing him to start a toy brand.
According to Animation World Network, Rumpus became "a company selling character-based plush toys online, backed up by Flash-animated segments featuring [Schwarz's] characters.
Each year, the titans scramble to fight their way on board the annual blockbuster movie train, recycle plastic space heroes or tired teddy bears and, of course, smother the market with endless variations of the golden girl herself.
Sadly, licensing has come to dominate the industry, and the role of the toy company as an innovative creator has become an increasingly neglected niche.
With a staff of 36 in a polka-dotted company headquarters in the Flatiron District,[4] Schwarz founded the Rumpus website, which housed toy sales as well as original Flash animations produced in-house.
[6][12] Schwarz's goal was for Rumpus to become an entertainment brand that created animated films alongside toy sales, "like Disney.
The studio produced Kappa Mikey (and its spin-off Dancing Sushi), Thumb Wrestling Federation, Leader Dog: The Series, Tortellini Western: The Series, Three Delivery, and Speed Racer: The Next Generation for Nicktoons Network and Ellen's Acres, HTDT, and Princess Natasha for Cartoon Network.
