The following is the solution to the safe in bedroom (Noah's Ark Puzzle). The order of the animals is as follows: Crab, Deer, Bear, any of the others in any order, then the Eagle is the last animal to enter.

Note: If you cannot get the safe open in the Noah's Ark after you have put the animals in correctly, you have to look at the pictures on the wall by the joker poker game first, and Sherlock has to comment on them. Also, the joker game must be done first.
