Uglydoll wiki

Moxy was created as OX's younger sister in 2006, the same year the Uglydolls won the Specialty Toy of the Year award by the Toy Industry Association.

Official Description

Moxy's got a lot of "moxy". She's got far more energy than her older brother, OX. Moxy's favorite activity seems to be bouncing off the walls and jumping in and out of mischief. Her giant antennae are always on the lookout for a good time, and she can hear a party from miles away. She can take care of pretty much any problem you may have, it's a gift of hers.
