Jack was a guest in 10 Minute Power Hour in the episodes Trivia Time (ft. Trivia Boy), Tie Dye For Real (ft. Jacksepticeye?), No Thumbs, No Problem (ft. Jacksepticeye) and Yeti In My Spaghetti (ft. Finn Wolfhard & Jacksepticeye).

Ninja Sex Party[]

Jack starred in the music video for the Ninja Sex Party song "Cool Patrol". In the video he is shown being bullied in a roller blading rink when Danny attempts to teach him how to be cool and stand up to them. However, his instruction proves unhelpful, as his character is implied to be killed by the bullies off-screen.
