Pikmin 2 Co-Op was Stephen's first (non-Demo Fridays) collaboration. It was a collaboration with Chuggaaconroy, and aired on Chugga's channel from April 11th, 2013 to April 13th, 2013. Stephen plays as Louie and Chugga plays as Olimar.
Stephen and Chuggaaconroy play Pikmin 2 co-op, going through the Cavernous Abyss, Bully Den, Sniper Room, and Emperor's Realm.
Stephen and Chuggaaconroy play against each other in Pikmin and Stephen makes more Pikmin than Chugga and wins the match.
