The buckets of Sloths is exactly what it says - Showing a party time bucket full of sloths. They hug each other and play with each other but mainly just lay down in a lazy manner. that's usually sloths do anyway.
The video is done by Lucy Cooke to celebrate the launch of her first book 'A Little Book of Sloth'. The book contains pictures, facts and data about sloths and a great story of how they live in the first sloth orphanage. A percentage of all sales goes towards sloths conversation and support the animals directly. You can order the book here:
