The Zhu Zhu pets are taking aim at boys by creating a new line of Kung Zhu pets, that are already hitting the bestseller’s list on stores nationwide (when they can keep them in stock). They’re promising to be one of THE hottest toys for Christmas 2010.

The new Kung Zhu Ninja Warrior Hamsters can be trained to do battle with each other, while they’re wearing their special Kung Zhu Battle Armor. They’re not your cuddly Zhu Zhu pets, but a new battle ready line!

There’s also a new Kung Zhu Battle Arena coming out in July, so your Kung Zhu hamsters can get together and do battle once they’ve been trained.

There are also special training toys, and vehicles to go with the new Kung Zhu line.
