|Conveniently, he's big enough to operate the pedals.|
Stumpy is an NPC operating the pedals within the Blast Furnace on World 358. Players can speak to him to learn about operating the furnace.
Speaking to him or his brothers, Dumpy and Pumpy, will reveal that they have a rare genetic condition that makes them unusually tall. The player points this out, but he will say that this condition benefits them by allowing them to efficiently operate the blast furnace.
