Wish: I wish I could fly.
Corruption: Poof... you can fly, but you fly right into a storm cloud and get electricuted.
Ok, I'll start.
I wish I were a size 2.
Reason: Moved to games forum
I wish I could meet Paul McCartney.
You do meet Paul McCartney but...ah man, do I really have to corrupt this?, but...you must enter into a yellow submarine, which terrifies you and there is a weird girl with kalaidescope eyes, which further terrifies you and then your guitar starts gently weeping.
You are so overcome with sadness.
I wish I had a yellow non-toxic highlighter I could apply to people I really really like, so everybody would know they were special.
