Old Nicky

Old Nicky is an NPC within the Guardian. It's inferred he has taken care of the Guardian since the Ro-War started, and has not stopped despite not knowing if it had ended or not. It seems he knows more than he lets on. If you give him the Fissure Soda drinking hat from the hidden room behind a noncollide wall in Fissure Outpost, he will take you to the depth dream orb for the Garden of Fulfillment.

Trivia

 * When you eat the Cheezburger in front of Old Nicky, he has a chance to say "please give me the big mac".
