Hickory, Dickory and Dock are a trio of mice featured in the Mother Goose Stories episode "Hickory Dickory Dock."
Among them, Hickory (Mak Wilson) is the troublemaker; he urges his two siblings to explore the house when their mother is away. The three mice make their way through May's house. They are startled and intrigued at first by the ticking of a tall clock, but the snooty clock ignores them and they gradually grow bolder.
Hickory goes so far as to climb the clock; however the climbing of a furry mouse tickles the clock and causes it to sneeze, striking one o'clock. With a squeal of terror, Hickory runs down the clock as fast as he can.
Dickory is performed by Karen Prell and Dock is performed by Mike Quinn.
