I wish for a voodoo doll.

[LadySigyn]

Granted, but it's a voodoo doll of yourself.

I wish I could control my dreams- which is possible I'm just unable to do it yet.

[Ame88]

[A.P.S.]

Granted, but instead of water, it's ketchup mixed in.

[FlyingGrass]

Granted, but you suddenly start playing every song backwards too.

I wish my robot character, Gui, was in real life.

[ShapesNBeats]
