Step 2: Room 8 Puzzle Solution
When you enter Room 8, here’s what you’ll find:
- Eight bins, each labeled with a different sin (like Greed).
- A painting of a fin hanging on the left wall and a rug made of skin on the floor.
- On the right next to the door, you’ll see eight animal statues, each one has a small clue or phrase written on it.
The clues are:
- Penguin: The sum of my sin, as it is penned, is a number within the room we are in
- Lion: To first begin, place me within a bin with an “N” within its sin
- Swan: I recommend you think again if I am ever in a bin far from the fin
- Dog: You won’t find my bin in between sin, for I deserve to be in a bin down on the end
- Elephant: To my chagrin, my neighbor’s sin is written thin to fit it all in
- Rabbit: I share a trend with my neighbor’s sin: a letter and its twin appear on each bin
- Bear: If we spend a min or ten lounging in the den, you’ll know which bin I’m often in
- Monkey: The bin I tend to wind up in is near the bend in the tail of the skin
