A tour guide captured the moment a child zooming on a zip-line through a rainforest in La Fortuna, Costa Rica, collided into a slow-moving sloth clinging to the cable. “The sloth or child weren’t hurt, and they just had to wait for the sloth to get out of the way for around 15 minutes,” Flavio Leiton Ramos, owner of Go.Adventure Arenal Park said.
