Game On.

Key

Once they were all on the floor, the world seemed to become the right way up. No longer did everything look upside down and confusing. The chandelier was the right way up, and it illuminated a simply decorated room with a checked floor, table and chair in the center and a tiny door, more of a dog flap in size, on one wall.
On the table, surprise surprise, was a cake and a small glass bottle.
Moira walked over. "Don't tell me, one makes us big and the other makes us small."
"There's no way I'm eating or drinking anything provided by a shadowman." Said Lindsay, shuddering. "Cat's proof of that."

A note with gold wording appeared in front of them.
One key, one choice.
Suddenly, the cake and the bottle shimmered and turned into two keys, one sugar pink like the cake, the other made to look like glass.

Cat bit her lip. The meaning was clear enough. One of the keys would fit the door, but they only got one guess. She dreaded to think what would happen if they chose wrong.
Valerian spoke up. "Well, obviously it's the one that makes you shrink. The doors tiny! And isn't that kinda how it works in the book?"
"Yeah, but that's really obvious." Said Moira "Besides, do you remember which one made her shrink?"
"The cake. No, wait, the bottle. No... arghhh! I don't know! Alice consumes both, it's hard!"
"Well, there has to be some way to work it out logically." Argued Lindsay.
Cat chewed her lip, dredging up all she could remember of Alice in wonderland.
Alice finds a table like this one, on it are the cake, the bottle and the key.
But the cake and the bottle are now keys, that doesn't help!
The only other thing on that table is the note!

The note.
