Haha I don't know why my mind also immediately went to Mr Meeseeks but my first thought was a mode where you have to unleash as many as possible by hitting switches, which crowds the screen with a bunch of Mr Meeseekses, who get antsy and start trying to kill themselves. The mode ends when Jerry gets the ball in the cup.
The video mode could be Roy: A Life Well Lived, where you make small, simple decisions that either lead to more decisions or an outlandish death.
