I just had to take a minute to post the cutest video I have ever seen in my whole life because you NEED to see it. If I were an animal I would probably be a sloth. These little guys are inspiring me to make some slothy things. Sloth backpack perhaps?
(the video has an ad in the beginning, but there is a "skip this ad" button to the top left)
The Sloth Sanctuary of Costa Rica is where these little guys live. They have a pretty amazing website where you can adopt a sloth or volunteer (www.slothrescue.org) I would recommend going and taking a look at the slothbook.
