What really interested me about this book, though, is that the version published in the US, Inky the Indigo Fairy, has a different name from the original version published in the UK, Izzy the Indigo Fairy. Izzy is not an uncommon name in America, so why the change? I got to wondering how else the books might differ...

Saffron was trapped in one of Mrs. Merry's beehives. Yellow butterflies fall from her wand. She has short blonde hair and wears a yellow t-shirt with a butterfly in the corner, yellow shorts with a butterfly at the bottom, and yellow trainers. In the books, she is quite troublesome, causing mischief wherever she goes. This happens in the land of sweets when she turns the lemonade indigo, and a gingerbread man's bowtie indigo. Of the seven Rainbow Fairies books, Izzy's book underwent the most changes when it was published in the US, mostly minor terminology edits for things that might be unfamiliar to American children. Toffee became caramel, Cornet's name was changed to Cone, currants became chocolate chips, and lemon sherbet became cocoa powder. Spelling was also country-specific. British "colour" versus American "color", "realised" versus "realized". it's literally like "such a wonderful secret, we have to save the world. also a wonderful secret: fairyland is gray"Amber was trapped in a creamy orange scallop shell. Orange bubbles emanate from her wand. She has flame-colored hair tied up with peach blossoms and wears an orange catsuit with long boots. I just realized that idk if the goblin's genders have ever been specified idk they might've but if they haven't I feel bad because I've been misgendering them Sue Bentley was born in Northampton, England. She worked in a library after completing her education and began writing for children once her own began school. Bentley is the author of the Magic Kitten, Magic Puppy, and S Club series and lives in Northamptonshire.

Izzy is the mascot for the Rainbow Fairies series and every Holiday Special book in the traditional layout. The goblins had tied Inky’s sneakers together with strawberry licorice. They were dragging her up the road, toward the jelly bean fields." Izzy's adventure takes place in the land of Sweets, in this adventure the girls and Izzy meet the sugarplum fairy, elves, gingerbread men, and travel in a pink bubblegum balloon.

Daisy Meadows is the pseudonym used for the four writers of the Rainbow Magic children's series: Narinder Dhami, Sue Bentley, Linda Chapman, and Sue Mongredien. Rainbow Magic features differing groups of fairies as main characters, including the Jewel fairies, Weather fairies, Pet fairies, Petal fairies, and Sporty fairies. This book deviates from the formulaic storytelling of previous books in the series. Instead of finding a fairy somewhere on the island, the girls are magically transported to the Land of Sweets. There, they meet all sorts of candy characters, which makes for fun reading. The goblins are there, too, and this time, they even get so far as to carry Izzy / Inky off! Izzy may have originally been called Inky in the UK during the series' original release, but her name was changed in every subsequent release as some UK editions exist with ‘Inky’.
