There's a Monster under Hansen Natural's (NASDAQ:HANS) bed, and it's mauling the analysts. The company behind the Monster Energy canned drinks generated fizzy, caffeinated second-quarter results this morning. Net sales soared 57% to hit $244.8 million. Back out costs incurred by the company's stock-option investigation, and a termination fee associated with tapping Anheuser-Busch (NYSE:BUD) as its new distributor, and earnings leapt 68% to $0.47 per share.

Red Bull-sipping pros clearly didn't see it coming. They were looking for the company to earn just $0.36 a share on $217.7 million in net sales. Either they failed to grasp the wingspan of Anheuser-Busch's distribution reach, or their channel checks were limited to the oversized cans of Monster Energy.

Pop stars like Coca-Cola (NYSE:KO) and the recently dethroned Jones Soda (NASDAQ:JSDA) are trying to make bigger plays in the energy-drink market. But Hansen's got a great brand, and it's not afraid to expand it.

Hansen introduced the non-carbonated Java Monster for the ready-to-drink chilled-coffee market at the start of the second quarter. Starbucks (NASDAQ:SBUX) may not be quivering in its bean-grinding booties over the assault on its Frappuccino, but Hansen is still a small enough company that even a minor hit in the coffee field could make a difference.

Hansen also introduced the M-80 line earlier this year, adding a juice-flavored bent to its invigorating energy drinks.

I've been skeptical about Hansen in the past. When I saw Coke put a little marketing muscle behind its Full Throttle brand, I thought that Monster would be in for a world of hurt. It obviously didn't pour out that way. Other potential Monster slayers, like PepsiCo's (NYSE:PEP) SoBe Energy or the Coke-distributed Rockstar, have tried to rattle the marketplace, with little success.

The energy-drink market belongs to Red Bull and Hansen's Monster. Everyone else is just fighting for scraps in the sandbox. What will it take before Coke or Pepsi wakes up and smells the taurine? If the Monster can't be slain, it's just a matter of paying $5 billion to $6 billion for Hansen today -- or $8 billion to $9 billion tomorrow.
