Skeleton Guy is a minifigure from Series 14.
There the Skeleton Guy was, out trick-or-treating one dark Halloween night, when he suddenly found himself in a land of real-life witches and ghosts and vampires. He doesn't dare to take off his costume and reveal that he's just a regular person underneath, so he's doing his best to pretend to be a monster too, and hoping that he won't be discovered.
But what the Skeleton Guy doesn't realize is that he isn't actually fooling anyone. Everybody knows that he isn't really a monster (after all, you can't fool a werewolf's nose), but they also don't care. He seems to be a nice fellow, if a little strange, so as long as he keeps being a friendly neighbor, the other monsters think that he can dress up however he likes!
The Skeleton Guy is available by Series 14 codes, which can be found in Series 14 blind bags in real life.
Parts can be dropped for the Skeleton Guy after completing the Monster Trials.
