Mr. Silly lives in Nonsenseland, where the trees have red leaves and the grass is blue. Every year there is a contest for the silliest idea of the year, and Mr. Silly can't think of one. All the animals do human activity and say the wrong sounds. Mr. Silly wins the contest by painting all the leaves on the trees green. <nowiki>Insert non-formatted text hereInsert non-formatted text here</nowiki>
