Sloths are very calm and very slow animals that spend their days hanging from trees. Michele, however, is a young sloth a bit special: he has bright green eyes, gets up early in the morning, and the slowness of the other sloth bores him. Michele's father is very worried about his son who is so active, and the other sloths are also unhappy. But when a fire breaks out in the forest, Michele's speed will prove to be a precious resource for everyone, and finally his father will understand that his son's diversity is invaluable.
