Editing Ivor the Engine (section)

===Idris the Dragon===
A small, red Welsh [[dragon]] who also sings in the choir for a time. Having been hatched from an egg in Ivor's fire, he lives with his wife Olwen and their twins, Daian and Blodwen, in the extinct volcano ''Smoke Hill''. As well as singing, he proves useful by cooking fish and chips for the choir using his fiery breath.

On the other hand, Idris runs into trouble when Smoke Hill goes cold and needs to be kept hot in order to survive. The gasboard provide a temporary furnace, but when that became too expensive (and decimalisation renders the slot-machine inoperable), the only other option for the dragons is a heated cage. Luckily, Mr Dinwiddy is able to provide a solution, and they now live in a geothermally-heated cave under the ground.
