Western pop stars log a lot of hours trying to invent new ways to be weird — I’m looking at you Lady Gaga. But for all the meat dresses and machine-gun bras and arriving at events in an egg, K-Pop acts seem to trump American oddity naturally.

Nicely, Gaga subscribes to the if-you-can’t-beat-them-have-them-join-you philosophy and has added Korean stars Crayon Pop to her ArtRave tour, which stops at the TD Garden on Monday.

After a 20-hour flight and still preparing to open Gaga’s gig in Milwaukee two days ago, the K-Pop girl group couldn’t hide their enthusiasm for their host and 15 stateside tour dates.

“Hello! Hello! We are Crayon Pop!” Ellin, Soyul, Gummi, Choa and Way shouted in unison into the phone before retreating behind a translator.

“We think it’s unbelievable to be touring with Lady Gaga,” Ellin said. “We have been fans of Lady Gaga since we were young. In interviews we have said that we would love to collaborate with her. Now here we are, a dream come true.”

Gaga likely got hip to the quartet the same time everyone else did: When Crayon Pop’s “Bar Bar Bar” video blew up last summer. And here is where the weird comes crashing in.

Unlike most K-Pop girl groups, Crayon Pop don’t peddle their looks. Instead the women have captured ears and eyes with quirky dances, Crayola-colored outfits and matching scooter helmets — the helmets are their signature look.

In the “Bar Bar Bar” videos, which have been streamed 25 million times on YouTube alone, the five bounce up and down like pistons in an engine wearing bright track jackets and brighter smiles. Dubbed the “Straight-Five-Engine Dance,” their moves have gone viral.

“There have been so many cover videos of our song,” Way said. “One of our favorites was an elementary school of more than 150 students imitating us on a playground. And then there are military guys covering us in lots of videos. It’s very flattering.”

Right now Crayon Pop are the Spice Girls after “Wannabe,” well, at least in the Asian markets they are. It’s a long way from one smash to global stardom. The Gaga tour should give them a fresh push. Then in the fall the women will launch another video.

But they’re also enjoying the ride. OK, not the 20-hour plane ride ahead of three weeks on the road in the States, but the fame and fun.

“We thought the first video (for ‘Bar Bar Bar’) was pretty good and energetic, but we didn’t know it would go viral,” Ellin said. “That was a surprise to everyone.”
