Who is Billy?
Billy was born from a child's pure imagination: first he was a drawing made with one finger on a drawing board, then he came to life in 3D. See the before and after → In his world, he's a magical creature who lives somewhere between the toys and the imagination — a loving buddy who shows up to bring comfort, joy and courage.
Personality
- Curious explorer: he wants to find out how every toy works.
- Shy, but loving: he hesitates at first, hides behind his teddy bear… and then gives the tightest hug ever.
- An open book: his feelings show up in his ears and cheeks. He can't hide them!
- Loyal and fun: a guardian of playtime.
Details that tell stories
Every part of Billy has a reason
The rainbow lock
Green, yellow, orange, red and a touch of purple: all the colors of feelings, falling right over his little face.
Two different eyes
One dark eye and one golden-brown eye (heterochromia). Being different is part of his charm.
The tummy stitch
A keepsake from the original drawing: it shows that every imperfection matters and carries the story of who we are.
