Champagne and the Mask are for scenes, and the bells and the candies are for the Christmas layout of the Nightclub. (Christmas ornaments have to be bought in Maries shop then you equip it in Desk setup) and champagne is for Fexa. (you place it in her room when she leaves it) and the mask is for Frenni. (from your office, go left and theres a door, open that up, and be there, but the power must be off first for anything special to happen.)
