Holly is the daughter of Vixen and Frost and a reindeer-trainee of Santa Claus who first appeared in the My Friends Tigger & Pooh Christmas special Pooh's Super Sleuth Christmas Movie. She was voiced by Mikaila Baumel. Holly paid a visit to the Hundred Acre Wood because Santa Claus had dropped his magic bag in which he kept all his toys there. She got trapped in some brambles and was rescued by the Super Sleuths. After this, she joined the Sleuths and the other members of the Hundred Acre Wood on a journey to the North Pole to return the bag to Santa. Along the way, they learned that Holly could not yet fly and this was the reason why she was only a reindeer-trainee rather than a full-fledged member of Santa's team of reindeer. When they eventually reached the North Pole, Holly flew for the first time and became a member of the team.
Holly reappeared in the story "Home For the Holly Days," in which she paid a visit to the Hundred Acre Wood during the summer-time and found herself missing the familiar reindeer games. Her new friends showed her how to have a good time in any kind of weather.
