His arms and legs were left bare and the skin of one arm was bright yellow and the skin of the other arm a vivid green.

He had one blue leg and one pink one, while both his feet--which showed through the open sandals he wore--were jet black.
Betsy could not decide whether these gorgeous colors were dyes or the natural tints of the skin, but while she was thinking it over the man who had been called "Tubekins" said: "Follow me to the Residence--all of you!" But just then a Voice exclaimed: "Here's another of them, Tubekins, lying in the water of the fountain." "Gracious!" cried Betsy; "it must be Tik-Tok, and he'll drown." "Water is a bad thing for his clockworks, anyway," agreed Shaggy, as with one accord they all started for the fountain.

But before they could reach it, invisible hands raised Tik-Tok from the marble basin and set him upon his feet beside it, water dripping from every joint of his copper body.
"Ma--ny tha--tha--tha--thanks!" he said; and then his copper jaws clicked together and he could say no more.

He next made an attempt to walk but after several awkward trials found he could not move his joints.
Peals of jeering laughter from persons unseen greeted Tik-Tok's failure, and the new arrivals in this strange land found it very uncomfortable to realize that there were many creatures around them who were invisible, yet could be heard plainly.
"Shall I wind him up ?" asked Betsy, feeling very sorry for Tik-Tok.
"I think his machinery is wound; but he needs oiling," replied Shaggy.
At once an oil-can appeared before him, held on a level with his eyes by some unseen hand.

Shaggy took the can and tried to oil Tik-Tok's joints.
