i'm so excited that you even indicated this was a possibility! truffle chair tops my list of decorations, but i mostly voted for the ovens on this poll. i would also LOVE the winter oven (that's straight winter, not any of the other ones with winter in the name) and the candy hatchery, and would appreciate the puebla & jazz ovens, musical drink machine, & healthy sweets (or decorations that use the parts for that second list of ovens so that i can get rid of them from my inventory--i'm really kind of ocd about this, and it's driving me nuts).
if i could unlock any other decor besides the truffle chair (love that thing), it would be the halloween mummy baker, vampire baker & frankenstein table.
