Yes, carrots can be creepy, at least a little. If you are looking for a creepy, but not very creepy, book to delight 3 to 6 year olds, I recommend Creepy Carrots. Although this is not a Halloween book, the illustrations, which feature the colors black and orange, and the slightly scary story, make it a terrific Halloween read aloud. The author is Aaron Reynolds and the illustrator is Peter Brown. Creepy Carrots has been recognized as a 2013 Caldecott Honor Book for picture book illustration.
