I wish to have a rainbow of fluffy jackets.

Granted, but they smell like rotten flesh and you can't get the smell out ; - ;

I wish I could make galleons appear in my hand from thin air, without anyone realizing

Granted, but anything you buy with the galleons disappears after a day.

Granted, but every time you become invisible/revisible there's a loud alarm noise

I wish I were an animagus

Granted, but you could only turn into a weak little worm

I wish I could try escargot

Granted, but you hate it that was easy

I wish for more fun hobbies Because running, drawing, swimming, knitting, reading, cooking, and all my other hobbies aren't enough

Granted but every time you try your new hobby you get injured

I wish for a unicorn

Granted, but it will disappear in moments.

I wish for a trillion - no, sextillion dollars.
