In the image you can see twelve mutation chambers (A to L). Each alien on the left side of the aliens goes through the three mutation chambers of its right side. The alien on the right side is the result after the three mutations. So, the alien left of chamber A goes through A, B and C. The result is the one right of C.
Same goes for the aliens op top. Every alien on the top of the image goes through the four mutation chambers below it. The one above A goes through A, D, G and J. The alien below chamber J is the result.
Every chamber applies exactly one mutation (make a head square, ...).
These mutations can occur:
- Add antennas
- Remove antennas
- Add arms
- Remove arms
- Add legs
- Remove legs
- Make square head
- Make round head
- Make square body
- Make round body
- Walk upright
- Walk on 4 legs (2 arms and 2 legs)
Each of these mutations can occur as many times as you want. It is not said that every mutation described above will occur for sure. This means that multiple chambers can remove leggs and that adding arms is done nowhere (e.g.).
Can you tell me which room provides which mutation? If you can tell me, tell me in spoiler tags!
