LEGO CUUSOO

Series 1 includes:
The Hatbox Ghost, Haunted Mansion Cast Members (Maid and Butler), the five singing busts, the Caretaker, Master Gracey, Madame Leota, Captain Culpepper Clyne, Constance Hatchaway, and the Hitchhiking Ghosts (Phineas, Ezra, and Gus).
Trivia: If you aren't familiar with the Hatbox Ghost it is more than likely due to the fact that he was removed from the Disneyland Mansion less than a year after the attraction opened because of technical difficulties. Rumor has it, however, that the Disney imagineers are planning on bringing the Hatbox Ghost back...

Series 2 includes:
The four main stretching portrait characters, graveyard trumpeter, graveyard bagpiper, headless knight, skeleton xylophonist, executioner, bride (Phantom Manor), cowardly sheriff, mayor (Phantom Manor), Phantom (Phantom Manor), the opera singing duo from the graveyard, and Great Caesar's Ghost (ballroom).

I know you can hardly contain yourself (like a certain ghost) but fear not: there are more series on the way! With 999 happy haunts, the possibilities are endless! Expect to see more characters from the graveyard, the ballroom, and even Phantom Manor...

"Ring of the bell, beat of the drum,
Some more familair faces are soon to come.
So hurry ba-ack and continue to drop by, too,
For we're always dying to see you."
