Nanny Plum is Holly, Daisy and Poppy's nanny and 'teacher', and a general housekeeper for the King and Queen. She is very good at magic and capable of speaking many animal languages (including ones which she claims to be a bit difficult such as Mole, Aardvark, Ant, Centipede and Alien). She often ends up into all kinds of trouble which she was trying to prevent Holly and friends from getting into. She is also a tooth fairy. She wears a purple dress and has black hair. Although being quite bossy, she is very good at cleaning with magic. She rivals the Wise Old Elf. She is a teacher at the Fairy School and also works as a maid.
