.. How to untie the knot?

It is! And F'ther only makes it messier!

That is correct. You need a knot expert!

Someone who is good with her hands.

Carol, go talk to Carol about the knots. You have to know what the knot looks like so try it first with F'thr. Try to describe the knot you left behind well.

You need a Writing utencil... like a pen?

Alex has a pencil. Go talk to him and ask for the pencil. Give it to Carol.

Great, now, just go back to the ladder and shout the instructions on the diagram to F'thr.

First, did you describe the knot correctly to Carol?
Use the following table to check that you have the correct description:

Knot	Description
	Two snakes fighting
	Little bit like Carol
	Mathematical formula
	Face like cow's udder
	Headache wearing a belt
	Lazy pole vaulter
	Cup of fingers

Good, this table will help you with the diagram:
