The Threadbare Excuse is a demon from the Mountains of Ignorance.
He is a small humanoid with extremely ripped clothing who clings on to everyone. He looks similar to Dobby from the Harry Potter series. He has a low, shrill voice and looks harmless to outsiders, and even friendly.
He seems to have a nervous, sensitive personality but he is also a liar, telling lies such as "I've been sick", "the page was torn out", "I missed the bus", and "no one else did it". He has a very strong grip.
