Go to the right and pick up a crank. Go back to the tentacle (to the left) and go one level down.
Use the crank with pink hole in the blue pipe. Turn the crank three times (Tommy will do the first one automatically). Go through the open door into the red room.
As Beak-Beak go to the tunnel. You will come to the room with octopus.
Look at the second (a bigger one) picture on the wall and remember it (it's the second hint to the random picture puzzle). Click on the octopus and see the story.
Finally swallow a mysterious yellow item, which now is lying on the floor. Go back to Tommy. Beak-Beak will throw out this item. As Tommy pick it up and use with the machine. As Beak-Beak activate the red button on the right side of the room.
Click Tommy and leave the room. Turn the crank 5 times and go to the green room.
Look at the moving animal fur. You will find a baby. Take another lever and leave the room.
The baby will start cry and the tentacle will run away. Click the baby. You need to solve the puzzle.
Push the green button on the left pipe. You need to play the melody on the carousel but there are 3 elements missing. The carousel has 9 elements, every one of them is playing a part of the melody. If you hang on one part in the wrong place, it'll fell while playing.
The solution is on the screenshot above. You need to wait as the light above the last toy will turn on.
Pick up a seagreen crystal.
