Costa Rica is known for its sand, sea and sun, but for one unlucky tourist it will have memories of crashing full speed into a sloth - leaving him stuck there for 15 minutes.
The unlucky boy collided with the animal within "30 seconds" of the sloth appearing, a tour guide has said.
The boy was zip-lining at popular Go Adventure Arenal Park, where adventurists can normally see monkeys, toucan and hummingbirds.
