FEAST YOUR EYES ON THIS, NEWGROUNDS! :D
Simply click on the pages to flip them, and use the little tabs on the left-hand side to navigate start to finish.
There's a lot of random stuff in here: hot babes, pokemon, left 4 dead, a naked dude, easter eggs... etc!
As opposed to the first Sabtastic Sketchbook which had only 48 pictures in it, I've managed to cram in over 60 pieces of original artwork this time!
Also, I've hidden a ton of mouse-over / click-able easter eggs so make sure you keep an eye out!
There are about 20+
Hint to find some of them: Boobs.
