Klaymen's cousin probably would like to help in this Idznak quest way more, only... he still sits in the Neverhood, eating his lunch.
But Wil has this amazing ability of collecting stuff that's yummy! And Klaymen can use this power in the form of... SUPER WILLIE!!!
So, whenever he uses this power, a giant head of Wil pops out of Klay's chest, collecting everything useful that's near - lifes, swirly Q's, and so on!
Wherrrrre you can meet Willie in the game: As said power-up in some levels, in the Intro and Ending movie and (my favorite!) on the main Options Screen, sometimes. o8-)
