Quite a while after Klaymen saved his dad Hoborg and so brought some happy life to the Neverhood, he suddenly gets kidnapped by a strange flying gizmo, right in the middle of his lunch together with his cousin Willie.
The journey leads to planet Idznak, home of the Skullmonkeys (which you should know by now o8-)
Now what Klaymen has to do is fighting his way through monkeys and Ynts to find out why he was brought there, and once he finds out he has to save his homeworld once again. Gee, wish him luck!
Where you can see him in the game? Er, well, you PLAY him! Also he's in the movies Intro, Beans, Sacret Root, Victoid, Ynt, Evil Engine and the Ending. And the Options Screen.
