Bed Time (1923)

First, Max, in his pyjamas, gets back up and draws an isolated mountain area and puts Koko on top of a steep mountain. "That will keep you busy for the night," says the real-life somewhat nasty cartoonist to his subject. The cartoon really gets wild from that point with guest appearances from Mutt and Jeff, and other "stars" of the day as Koko experiences one adventure after another from the "Cave Of The Winds" to Goliath chasing him all over.
