Make a Wish. Have it horribly corrupted.

[Nightmare Eater]

Granted.

I wish for a brick wall(you asked for harder wishes )

[spritey]

Granted but I smashed it into pieces. (Still too easy, and still too soft )

I wish for the person below to melt.

[OranBerrySandvich]

Granted, but I drip all over your food. You eat me. You're poisoned. You die.

I wish for 42 derps that are completely herp proof.

[Trekkie WhoLocked Fangirl!]

Granted but you only get 40       I wish for a large ice-cream...

[Nightmare Eater]

Granted but its Vanillite who is angry that you tried to eat.

I wish for walls.

[Kona]

You get walls, but they are made of flimsy rubber.

I wish for a pet Velociraptor named Earl.

[OranBerrySandvich]

Granted, but I also get a cloning machine. Seen Jurassic Park?

I wish that the Jurassic Park sequels were actually up to the standard of the first. And that I could watch them.

[Skyler and Blazer]

Granted. You go deaf on opening night however.

I wish I was better at math.

[ScottishFoldLover]

Granted, but now you forget how to do everything else.

I wish for some chocolate covered pretzels.

[Trekkie WhoLocked Fangirl!]

Granted... But thats not chocolate... Its gravy!     I wish I could fly

[ScottishFoldLover]

Granted, you are teleported to an airport where you can fly, but there is a huge delay and you have to sit around doing nothing.

I wish for a strawberry scented candle.

[Nightmare Eater]

Granted but the room you were in when you put it on was unfortunaly full of methane. Good news. The explosion smelled of strawberries.

I wish everyone shot a beam into one set spot and the blasts combined creating a show for everyone to see.

[Skyler and Blazer]

Granted, but you are at the center of the beams. Your body exploding will create a wonderful show for us all

I wish I cared about my fashion

[Nightmare Eater]

Granted but now you don't care about anything else.  Even your life. Someone tries to shoot you and you don't care.

I wish the Sun shot down a beam of light about an inch next to my arm so people everywhere would think I dodged it with super ninja speed.

[OranBerrySandvich]

Granted. What people think you didn't dodge with super ninja speed was the explosion from the nuke hit by the beam. You did. You accidentally jump off a cliff while didging instead. But you don't fall to your death. You land on a helicopter. An active one. An active one's heli-blades. You die.

I wish for pudding, and an unnecessarily convoluted corruption.
