I love animals, but the sloth is one of my absolute favorites. I've
seen one in a tree but I would just about die of joy to be as close as the one in the linked video. When I was in Costa Rica for a belated honeymoon a few years back, a woman at a wildlife sanctuary unexpectedly handed me an injured baby howler monkey to hold while she dealt with other business. An unbelievable experience. Brooklyn's squirrels have their charms, but it's not quite the same.
Extra bonus - baby platypi(?):
