Lily is the youngest sister of the Caillou family. She's sweet, caring, and a bundle of joy to everyone! She loves children's shows (Her favorite is The Amazing World of Gumball) and a huge fan of Anais Watterson!

Lily wasn't in the actual Caillou show she's a fanmade character. But in some universes Caillou (The Show) is years before she is born.

She has a youtube channel which how she got known in the first place. She reached tons of subs and made tons of friends along with her siblings!
