Mr. Nonsense lives in Nonsenseland, in a house on top of a tree. When asked why he sleeps in a rowing boat, the answer is "I tried sleeping in a motorboat and it was somewhat uncomfortable." When asked why he eats porridge on toast, the answer is, "I tried porridge sandwiches and I didn't like them." Mr. Nonsense is best friends with Mr. Silly, and when it snows yellow snow, they go for a toboggan in Mr. Nonsense's rowing boat bed. They build square snowballs somehow.
