Thomas has a scab on his arm, given to him by Beeps. He's been trying to get Rocky to remove it for him for a few days. You can see it off to Rocky's left:Here, Rocky's testing it, but it's not quite ready to go.
Both Rocky (for Thomas) and Calypso (for me) have amazing scab-removal skills. They test the scab daily and when it's ready to go, they painlessly remove it.
Of course, I would love to live in a world where this service was not needed. Less frequently every year, so that's a good thing!
