Frankenstein encounters creatures and objects with specific colour combinations. Plug the pipes into coloured heart nodes to match those combos.
Match the colour combos that come up on the right by plugging tubes into the coloured pipes.
Click on a pipe to detach it from the socket.
You can match any combination in the queue, but need to match them exactly.
Note: Green socket is a bit buggy at the moment, if it's not attaching just wiggle the cord around a bit when placed over it.
