Pipe-dwelling Demon

A pipe-dwelling demon or pipe-dwelling devil is a type of demon that inhabits a pipe. They can be found in pipes of all sizes, from sewer systems to smoking pipes.

Once in a pipe, these demons will cause all sorts of mischief to passersby. One common example is rendering all speech to a series of vile, hostile insults, making proper communication impossible. However, the demons are otherwise harmless, and can be easily driven out of their pipe by pouring wine on them. This makes them more annoying than anything else.

It was once theorized that bagpipes' distinctive sound was the result of pipe-dwelling demons, but this was later found to be incorrect.
