"Don't know," said Button-Bright.
The thing gave a jump and turned half around, sitting in the same place but with the other side of its body facing them. Instead of being black, it was now pure white, with a face like that of a clown in a circus and hair of a brilliant purple. The creature could bend either way, and its white toes now curled the same way the black ones on the other side had done.
"It has a face both front and back," whispered Dorothy, wonderingly; "only there's no back at all, but two fronts."
Having made the turn, the being sat motionless as before, while Toto barked louder at the white man than he had done at the black one.
"Once," said the shaggy man, "I had a jumping-jack like that, with two faces."
"Was it alive?" asked Button-Bright.
"No," replied the shaggy man; "it worked on strings, and was made of wood."
"Wonder if this works with strings," said Dorothy; but Polychrome cried "Look!" for another creature just like the first had suddenly appeared sitting on another rock, its black side toward them. The two twisted their heads around and showed a black face on the white side of one and a white face on the black side of the other.
"How curious," said Polychrome; "and how loose their heads seem to be! Are they friendly to us, do you think?"
