Harriet the Hamster Fairy is the 33rd book in the mainline Rainbow Magic series, and the 5th in the Pet Keeper Fairies series.
While pet-sitting, Rachel and Kirsty have to hunt down a runaway hamster.
Tropes:
- Dub Name Change: Portuguese prints change Harriet's name to Rita.
- Incredible Shrinking Man: Harriet's hamster Twinkle can shrink at will to fit into tight crevasses.
- Shout-Out: Rachel and Kirsty find an old lamp in the attic that they say resembles Aladdin's lamp.
