Good wishes aren't always good wishes

Granted, but you get eaten.

I wish I was Pikachu.
 
Granted. We all turn into lovable teddy bears and start choking each other to death.

I wish that whoever corrupts this wish can't make a wish.
 
Granted, you can't read anything else

I wish I was intelligent.
 
Granted, but no one likes you

I wish for lots of money
 
Granted, but Pokemon attack you for no reason

I wish I had a talent I was good at
