So I found this on Tumblr, where they have various 30-day challenges that go around.

I already found a 30 Day Harry Potter challenge, here's a link to the original:

But anyways, this is another one I found, different from the first.

Basically you start with answering Question 1, then come back each day and answer the next one until you're done.
Have fun!

Rule: In each of the following 30 prompts, you are stuck in a Harry Potter scenario. Post something interesting that has to do with the description - from your POV!

Day 1: You get to spend the day rollerblading and watching movies with your favorite character. Who is this character?

Day 2: You find a genie in a bottle and you wish to kill any one character in person. Who is it?
