Legend of the Missing Hat

I’m feeling kind of silly in that I cannot figure out this simple game. I have given green ninja the pearl, the red ninja the notebook and found the yarn in the mouse nest. I have an inclination that I’m supposed to get ontop of the desk but no idea how. i have no idea how to interact with the blue ninja.

You’re right; you need to get on the desk.

What do you have that seems climbable?

A rope would be nice.

Or, since you’re really tiny, a length of yarn.

But the yarn won’t attach itself to the desk.

Do you have anything that would help stick the yarn to the desk?

Something pointy… hell, I don’t know why I’m trying to be vague about this, you only have one other thing.

The shuriken and yarn together will work.

Explicit command:

TIE SHURIKEN TO YARN

Explicit command:

THROW HOOK AT DESK
