Editing Ivor the Engine (section)

===Mr Dinwiddy===
A very odd, possibly insane miner who lives in the hills and digs for gold. He enjoys explosions and mining. In fact, his mountain is full of gold, but as soon as he digs it up, he puts it back again. He often has need of new boots.

He is something of an amateur scientist. He describes himself as "educated" and knows "something about rock". He has constructed a few odd devices, including a donkey carriage and a bubble-blowing machine.
