Granted but the animals you speak to hate you

I wish for random stuff

A random anvil appears in the air above you and fall on your head.

I wish to go to study magic in Hogwarts.

Granted, a former follower of Voldemort bring him back to life and you die

I wish I had one million dollars that last a lifetime and I don't go bankrupt.

Wish granted! The million dollars will really last during your lifetime since it's locked in a highly secure unbreakable digital safe box, and you don't know the code to open it.

I wish for an immortal dog who can speak and who will love me and stay with me forever.

Granted, but soon people get jealous of your dog and exile you. You soon die of starvation and because the dog loves you so much, it tries to kill itself, but since it's immortal, it is constantly spending its days trying to kill itself.

I wish that me and my family and friends live untill we are 300.

(That's cruel for the dog!!!)

Wish granted...You will all live until you're 300... But you won't stay young and age as quicly as the other humans, so you'll already look very old at 100, and you'll continue to look older and older and to suffer more and more from the effects of old age after...

I wish for a medieval castle.

(I know, but you made it really hard. I would hate to see a dog do that though for all eternity... :'(

Granted, but the castle is haunted and it crumbles in an earthquake.

I wish for a perfect confederate dollar bill.

Ok, as a numismatic I don't want to be mean with this one. You've got a perfect confederate dollar bill, but it's one of the more common type of all of them.

But in exchange, I wish for a real Brutus' Ides of March Roman Denari in perfect itate of conservation (aka. The coin minted by Brutus to commemorate Julius Caesar assassination, which worth hundred thousands of dollars)!

BTW Confederate dollar bills are worth thousands of dollars, an they are never common. Just saying

Granted, but the coin breaks and you go bankrupt.

I wish for a endless supply of ice cream that doesn't melt, tastes good, and is healthy.

(It depends of WHICH type, and you didn't make any precision ;) if you look on the internet, some are for sell for less than 100 dollars. But for the rarest, yes, they worth a lot.)

Wish granted, but the endless supply of ice cream comes with an endless supply of annoying people who come to eat some ice cream or even try to steal your endless supply of icecream.

I wish to make a one year round-the-world-tour!
