The Wishing Game!

[FlyingGrass]

Granted, now Marx tells the truth to Kirby for summoning Nova, but everything else he says changes to a lie.

I wish the appendix is useful.

[FrostNight]

Wish granted! But with it, science also found the Appendix's job also causes aging in humans, and part of why we don't really live past 100 years.

I wish to live forever!

[Ellen11v]

Wish granted, but you'll have to suffer with watching all your family and friends die. And your favorite celebrities. And your children and grand children if you get those.

I wish I created an art masterpiece that people all over the country would love!

[Ame88]

Granted, but only in one country, and when everyone in that country sees it, the piece will spontaneously combust.

I wish I had a dog

[A.P.S.]

Granted, but you didn't specify living, so you now have a plushie.

I wish I could talk to my pets in normal English words.

[Ellen11v]

Granted, but overtime you'll get tired of them yelling at you everytime they need something.

I wish I've learned to speak Japanese

[Morqque]

Granted, but you cant read Japanese...only Roamaji.

I wish I had a nice, large plate of Sushi.

[FlyingGrass]

Granted, and it's humongous, it looks appetising, it smells excellent, and it's all yours... Except it's made of cardboard. There are some parts of it that are real, however... But finding it will take some rummaging amongst the newly-summoned pile of cardboard sushi, and there's a swarm of ants racing you to it.

I wish to engineer a mutant bearded dragon, and have it be tame.

[A.P.S.]

Granted, but it only lives for a day before killing over.

I wish I had the ability to make objects come to life, ideally in human form if not already.

[FrostNight]

Granted! But now you've released the pent up anger that's been accumulating in objects that, until now, had no way of acting on their aggressions. They're volatile. Be careful who you chose. Keep a safe distance. And be kind to your belongings.

I wish I was a genius in science.
