Christmas

Santa's on his way home from his holiday in Barbados but as usual he's left it rather late.
He plans to be back in time to fill the sleigh and deliver the presents.
Every year Mrs Claus hides Santa's key for the workshop as he's become rather forgetful recently. She makes a treasure hunt to help him remember the codes, to find the key to access the workshop.
So to save time, solve the puzzles and find the key, he will be back in an hour to deliver the presents, so hurry and good luck.
