Alpin · white monster
Brave, agile, a little too brave.
A white skiing yeti with bright blue eyes. Brave and adventurous — sometimes a little too much!
Book 3: Try Something New →Meet the monsters
(yes, they are all a little much)
Ten fuzzy friends, ten colors, ten very different ways of getting into trouble. Find your child’s twin, or yours.
The crew at a glance
Alpin is white, Rosalie pink, Lily green, Pluvie blue, Soleo yellow, Rusty orange, Maxo red, Fonzo mauve, Smoky black and Clay grey. Easy to spot, easy to love, and easy for little ones to name before they can read.
Each monster stands in for a toddler mood: the daredevil, the worrier, the snack hunter, the little boss. That makes them great social emotional books for preschoolers, because kids recognize themselves and laugh instead of getting defensive.
