Another cast member in the AC that appeared to me to be a Magic Kingdom Regular has the nickname of Leprechaun on the wiki:
much like the entry for ole stogie I mentioned in the previous post the
listing for leprechaun too seems to be a bit sparse in detail, though
he too looks familiar, and if I am correct he shares more in common
with "Old Stogie" than that, as he too is a member of Rusty Cutlass
and he is also a long time Dapper Dan, usually appearing in PURPLE
stripes. He is also probably the shortest of the Dapper Dans, and as such he is the recipiant of many short jokes when they are hamming it up, which would seem to tie in nicely with his Adventurers Club nickname as well, in fact it reminds me of a line I've seen Otis use on Emil Bleehall when he gets frustrated with him during the Balderdash cup competition... "get out of here you freaky little leprechaun", and since that is one of the roles he has played in makes a certain amount of sense that way as well.
