This is not the Cindy Lou Who you remember. She's all grown up and wreaking her own kind of havoc. In this play by Matthew Lombardo, Cindy Lou tells the story of everything that has happened since the Christmas Eve when she met the Grinch for the first time, according to Broadway Play Publishing Inc.'s official website. In its synopsis, the website says:

You saw her last when she was just two.
Celebrate the holidays with Cindy Lou Who.
Pull up a seat and fill up your cup
'Cause your favorite little Who is all grown up.
