Whether you know them as scoobies, rainbow looms, loom bands or Cra-Z-Loom, these coloured elastic bands have Rotorua kids (and a few adults) obsessed.
Since Kate, the Duchess of Cambridge was seen wearing a loom bracelet on her New Zealand tour, sales for looming kits have skyrocketed.
The simple elastic bands can be crafted into almost anything, from a simple friendship bracelet, to hats, pet collars or animal figurines.
With hundreds of tutorials on YouTube, it is easy for beginners to quickly pick up on the art.
Rotorua siblings Maia, 9, Aleyah, 11, and Graegan Horne, 9, started looming about a week ago and spend most their spare time crafting bracelets for mum, Kasey.
Aleyah said she had learnt how to make rings, bracelets, earrings and necklaces.
"When I'm bored I can just go into my room and make something instead of sitting around doing nothing.
"There are lots of different things you can make and there are different styles that you can learn like the fishtail-braid bracelet."
Graegan said it wasn't just an activity for girls to enjoy.
"I like it because it's something creative to do. Once I have practised some more I want to learn how to make animals because they look cool.
"You can also make it into a competition to see who can make the longest band."
But it is not just youngsters getting swept up in the craze, many adults are equally taken by the craft.
Amanda Bunn, 24, started looming when she saw children doing it at the daycare centre where she works.
"I originally brought some bands home for my kids but they weren't really interested, so I started making them myself and got hooked."
Ms Bunn said instead of reading a book at night, she now created loom jewellery.
"It's really addictive and I find it quite therapeutic. My kids will tell me what colours they want and I'll make them bracelets and necklaces, I made 10 last night."
Rotorua's AJ's Emporium has been swamped with loom band demands and has been restocking its supply each week.
Manager Sheryl Davy said it was a cheap craft that everybody could enjoy.
"It is getting the kids off the Xbox and doing something creative. It seems like every other customer is asking for packets of the elastic bands."
Ms Davy said the elastic bands were selling like wildfire and for $2 a packet, they "didn't break the bank".
"It's absolutely wonderful to see everybody getting into it. It's an activity that girls, boys and adults can enjoy."
