"Shorty" Smith is a deceased character found in the Boot Hill cemetery of Phantom Manor. They are mentioned on a tombstone which true to their nickname, appears to be comedically short.
"Shorty" was an individual who came to inhabit the town of Thunder Mesa by the 1860s. In 1862, Shorty died and was buried in the Boot Hill adjacent to the haunted Ravenswood Manor.
Shorty's tombstone was either created ridiculously short or sunk into the dirt, reflecting Shorty's crude nickname.
