Baby sloths are undeniably adorable — especially when they haven't quite figured out the whole "climbing" thing.
These slo-mo sloth babies are hanging out on their special jungle gym at the Sloth Sanctuary in Costa Rica. The babies are orphans, and are being cared for at the facility's NICU.
But the jungle gym (or exercise in any form, really) is not as fun as the two-toed sloths thought, so they voice their displeasure by squeaking adorably. Despite their complaining, they begrudgingly do their climbing exercises, giving their little limbs a proper workout.
