On the Caribbean coast of Costa Rica, some neighbourhood girls found a baby three toed sloth. Not knowing how to care for her, they took her to a nearby bird sanctuary owned by Judy and Louis Arroyo.

The arrival of this unexpected little guest, whom they named Buttercup, changed the destiny of Judy and Louis. When the community learned of their success in raising Buttercup, dozens of two-toed and three-toed sloths, who were found abandoned or injured, arrived at the centre.
