The three inept flower pixies are charged with caring for Aurora until her sixteenth birthday.
Knotgrass (Imelda Staunton) is a tangled knot of bad humour; a bossy superior to the other two pixies.
Flittle (Lesley Manville) is a blue flower pixie. She always has butterflies flying around her head.
Thistlewit (Juno Temple), the youngest of the pixies, is always giddy, playful and childlike.
