Winnie's Final Clue

Winnie has sent Wisty and Siobhan one final clue. It's a box with the item that she's been hunting down this entire time. The only bit that was seen by Olive giving a clue to what was inside was a piece of paper with a series of numbers on it.

5 Words: 6, 9, 5, 3, 6

Ok, so throughout all of Winnie's letters, certain letters have been highlighted. My guess is to take these letters and arrange them into five different words. These are the letters we have to work with.

IRHPUHWPYIQDOTEOUDOTDNTCLRCLS

The first word I see is QUIDDITCH. It's nine letters long and the whole reason we're for this round of HSKS.

Next, I see WORLD. A five letter word that goes well with QUIDDITCH. That leaves us with:

RHPPYEOUOTNTCLS

Now it gets a little harder. Lets try the three letter word first. Thinking back to The Goblet of Fire makes me think it might be CUP. This leaves these letters:

HRPYEOOTNTLS

Ok, so now we have QUIDDITCH WORLD CUP. Now I'm kind of stuck again. Time to seek some help from those who are good with anagrams and word problems. My grandma!

Yes! Grandma came through for me again! She sees STOLEN and TROPHY as the last two words. So what is the five word phrase for what is in the box from Winnie? The item she's been off searching all term?!

STOLEN QUIDDITCH WORLD CUP TROPHY!

Wow! What an adventure and great find! Way to go Winnie!
