You can get all your otto splotch needs met in one space at his new website:

http://www.ottosplotch.com/

Otto is the kind fellow who has drawn such things for us as, the dog logo, the head above water art, the art for the veggie oil van kickstarter, compilations (1,2, & 3), the dogzilla design and other things along the way. He rules. Most of his other art is totally gross. Be prepared to be grossed out. Yeahhhhhhhhhhhh
