In spite of his long-skirted coat he was as active as any of them, now clutching desperately at the eel with his hand, now running at full speed for a few yards and then plunging down on his knees, and all the while laughing and Whinnying with a noise more like that of a horse than of a man.

They will spring into the air, tumbling over, with Whinnying cries of delight, falling to the ground they pretend to bite and snap at everything, until their friend finally comes very near them.
"The Human Side of Animals"
