1, The group were formed in a 2017 reality TV show, also called Stray Kids. Nine idols had to compete to all stay in the band and debut as a team together. They succeeded, and the group launched in the same year! In August 2017, JYP Entertainment (JYPE) officially announced their new reality survival show with the goal of launching a male idol debut project. More details and teasers were released in the next two months, including the show's title, Stray Kids. Prior to its premiere on October 17, JYPE released Stray Kids' first music video for a song titled "Hellevator", which was later released as a digital single. Two members, Lee Know and Felix, were initially eliminated from the group but returned to the final nine-member line-up.

2, THERE USED TO BE NINE MEMBERS: The ninth member, Kim Woo Jin, left the band two years after debuting for personal reasons, trimming the group down to eight members.

3, One of them used to be in BTS! Lee Min Ho, aka Lee Know, used to be a backup dancer for international superstars BTS!

4, Two are from Australia! Leader Bang Chan was born in Seoul but raised in Sydney, Australia! He moved back to South Korea at the age of 13 to train under the record label JYP. Felix was born in Sydney, and also grew up there. Both of them have Australian citizenship, and are fluent in English!

5, Bang Chan is double-jointed! Bang Chan is seriously flexible! He has double-jointed arms, and demonstrated it on the reality show! This must come in useful for dancing, but maybe also in his old hobby, swimming! Bang Chan was a competitive swimmer in school, and at the age of eight, he broke a record at his school's swim carnival!

6, I.N. has a lot of nicknames. I.N. is already a nickname for Yang Jeong-in, but he's got lots of other names too! He's also known as Desert Fox, Our Maknae, Spoon Worm Yang, Fiona, Baby Bread and Bean Worm.

7, Han's had an interesting life! Han has several very interesting stories in his repertoire - and probably the most extraordinary is that he was once nearly eaten by a crocodile! Han lived in Malaysia for a while, and once when he was swimming in a jungle river he spotted the croc in the water. Luckily he was rescued by his dad's colleague - great news for K-pop fans everywhere! He also appeared in the Korean version of The Masked Singer, costumed as a legendary character from Korean history.

8, They love animals! The Stray Kids crew keep animals near and dear, and dogs are their preferred pets! Bang Chan has a dog named Berry, Han has a dog named Bbama, and Hyunjin has a dog named Kkami! I.N. doesn't own a dog at the moment, but says he loves them and can't wait to adopt a dachshund! Lee Know is more of a cat guy, with three kitties named Dori, Soonie and Doongie. And, while *technically* not a pet, Changbin has a Munchlax plushie he can't sleep without.

9, They have an official light stick!As you probably know, K-pop idols have their own light sticks, and Stray Kids have a special one! It's called the Nachimbong, and it's loaded with symbolism. "Nachimbong" is a play on the Korean words for "compass" and "rod". Compasses are featured a lot in Stray Kids' debut storyline, with a broken compass used to symbolise them becoming their own guides (check out the song "Mixtape#4"). It's also supposed to lead fans to the concerts!
