Curly is one of Dennis the Menace's best friends (along with Pie-Face), and is so called because of his curly hair. His real name is Crispin. He also mentions having a little brother called Spikey who was caught on Bath Night and by tomorrow had changed forever.
He has blonde curly hair, a yellow shirt, blue jeans and brown shoes.
In the Dennis the Menace television series, Curly was voiced by Jill Lidstone and Richard Ian Cox in the US.
