Toodee is the 4th member of Yo Gabba Gabba, as "She likes to have fun!" She is also the second female member of the group alongside Foofa. She has parents, as well as a little brother named Keedee. Toodee lives the appropriately named Toodee Land, a winter themed realm, next to Brobee Land.

Toodee is bold, self-confident, caring, loyal, and full with energy. She is also be a bit selfish, like that time when she cut in front of Foofa, that time she “borrowed” Brobee's ball, that time when she disapproved of Gooble’s crying. She mostly tends to her soft side when it comes to her friends and her. Toodee also has a big imagination and loves to pretend. Ice and snow is her biggest bond point, even discover something new and try new things too plus making new friends along the way, but hates it when they have to see them go. Toodee is also shown to have some leadership in her friends even being adventurous, from that time she lead the group up on Gabba Mountain and got a special badge from Barbara. She is the most athletic out of her friends as seen in the activates she does; ice skating, surfing, and getting exercise, depicting tomboy traits. She can also tap dance. However, she lacks artistic skills.

She is a half-cat/dragon hybrid with an oval-shaped body of a mellow blue furry coat with a lighter shade on her whiskers and stomach covering her mouth. Toodee also has fangs, long eyelashes, and rounded scales on her back to her tail, symbolizing dragon features.
