Zhu Zhu Princess Magical Princess Castle from Cepia, LLC

Since Zhu Zhu Pets were introduced in 2009, the "Zhu-niverse," as they call it, has continued to expand. This year the electronic hamsters get girly with the Zhu Zhu Princess line. One of the main playsets in the line is the Magical Princess Castle. Place a hamster at the entrance to the castle, press down and watch the hamster scurry inside to explore the castle. http://www.timetoplaymag.com/toys/2343/cepia-llc/zhu-zhu-princess-magical-princess-castle/
