The sloths are coming, and they are coming by bus.
A daily dose of exercise is all well and good, but sometimes it's quicker to get the bus, and this sloth certainly thought so.
The brown-throated sloth was spotted by tourists, looking rather unwell while stretched out and motionless on the forest floor in Costa Rica.
She was feeling so below par that even when the do-gooding day-trippers tried to pick her up and put her back in her tree, she just collapsed in a listless lump.
Close to a nearby sloth sanctuary, their tour guide suggested she be dropped off on their way home.
Californian photographer Suzi Esterhas took the snap. She told the Daily Mail: “I was photographing sloths at the Aviarios Sloth Sanctuary when we received word of a new arrival.
“When the bus arrived, I asked the driver where the sloth was and he said 'She's ON the bus!'
“The female (sloth) instinctively wanted to climb on the railing of the seat on the bus, where she rode for the journey to the sanctuary.
'It was all very cute. The driver, guide and tourist seemed so genuinely concerned about her wellbeing.”
The female sloth was nursed back to health and rehydrated ready to be released back into the wild.
The sloths at Aviarios Sloth Sanctuary are currently featuring in documentary made by Lucy Cooke. Any sloth in need of a helping toe or three is taken in at the orphanage, but mainly it is baby sloths whose mothers have killed.
Cooke talked to Huffington Post about the Aviarios Sloth Sanctuary, run by celebrated sloth whisperer Judy Arroyo and home to over 160 sloths.
"Judy does her best to be a sloth mum and teach the babies how to be a sloth - potty training and how to climb are key parts of their sloth school curriculum.
"But at present she doesn't know how to teach them what leaves are safe to eat. The Costa Rican jungle is a veritable pharmacy of toxic trees and sloths are adapted to eat just a handful of species."
The hour long programme “Too Cute! Baby Sloths” is being shown 17 December at 8pm ET on Animal Planet.
"The sloths are coming" video is the preview to the show, which instantly became a YouTube hit.
Sloths are so slow that although their hair is light brown algae grows on their coats making them look green.
They sleep for up to 18 hours a day in the wild, curled up in a ball so their natural predator, the jaguar, will not spot them.
The “Too Cute! Baby Sloths” documentary shows one sloth on his quest to mate, but apparently sloths are short changed. In the one department where slowness can be an asset, sloths missed out:
“It turns out that sex is the only thing a sloth does swiftly” Cooke says.
