GUESS WHOOOO!!!

Hello Reuben and Phoenix - isn't this a surprise!
I've done it again, as I'm sure you've surmised:
I've taken the prezzies! I've hid them away!
And I reckon I'll get a fair bit on eBay...

BUT as you know by now, I love a good game
So if you can find me (which would be a shame)
Then I'll give you them back and we'll call it a draw
But can you do it in time? I'm not so sure...

You've got 10 whole minutes to follow these clues
Before I do what the Grinch almost did to those Whos!
Simply enter each code to unlock the next clue
Are you ready? Then let's do it - I'm waiting for you!
