Drawing Octo was fun. 

Octo can scratch your back, keep an eye on you, and choke out your enemies. Octo lives in the dark and glows in the dark, and thanks to its regenerative abilities, it’s immortal. It’s Rad.

Octo is available in many many wonderful versions, including tees, hoodies, posters, smartphone accessories, various prints and posters, even mugs and bags. Buy it at Redbubble and Society6.
