Technically, there's no medical reason for this tortoise to be bathed, The Telegraph reports. But Jonathan's keepers thought everything, including the resident tortoise, could use a washing up before a member of the British royal family visits the island in May.
Indeed, while Jonathan will continue being the same old giant tortoise - we hope for many more years - it's the man who gave him the bath who seems the most profoundly affected.
"What an honor," Hollins says in the video at the scrubbing's conclusion, "to be looking after the oldest living land animal. What an amazing thing."
