The above photo shows Dr Peter Whimbrel in his immature form; it was before colour TV was invented and people still lived in black and white. His parents, Skulduggery and Miasma Whimbrel, were nevertheless delighted that he had managed to power a single lightbulb by the simple expedient of attaching a dynamo to his pet rat's exercise wheel. His invention of the treadmill followed soon afterwards, long before anyone had thought of making him a doctor.
As you can see, he was as much of a nutter then as he is now, though his distinctive tapir-like proboscis was only in its formative stage.
He is shown here trying to grow the fingers of his fingerless gloves, using only the power of his personality and his funny little squinty eyes.
