Cindy Lou Who is a sweet young girl from Whoville and one of the main characters from the computer-animated Dr. Seuss' The Grinch. She is voiced by Cameron Seely, who was in the movie The Greatest Showman.
Cindy-Lou is an energetic and hopeful young girl with a firm belief in the spirit of Christmas. She is smart, cunning and inventive. She constantly comes up with sophisticated plans of how to do something simple and always knows the best way to solve problems.
Looking for a way to help her mother, she plots to capture Santa Claus, something which will interfere with the Grinch's plans.
Of course, Cindy-Lou loves presents, but she knows that being nice, and spending time with those you care about is the best thing of all, a gift that can be given every single day, no matter what time of year it is.
