Whitefoot The Wood Mouse in "A Very Careless Jump"

He had been running and jumping all around the inside of the little sugar-house. He loves to run and jump, and he had been having just the best time ever. Finally Whitefoot ran along the old bench and jumped from the end of it for a box standing on end, which Farmer Brown's boy sometimes used to sit on. It wasn't a very long jump, but somehow Whitefoot misjudged it. He was heedless, and he didn't jump quite far enough. Right beside that box was a tin pail half filled with sap. Instead of landing on the box, Whitefoot landed with a splash in that
pail of sap.
