Pepsi and Cheetos may seem like a good combo for an after-school snack, but Frito-Lay have taken things one step further with a Cheeto that is actually Pepsi-flavored.

The crunchy puffed corn bites are only available in Japan so far, and the company reportedly doesn’t have any plans to put them on shelves in the U.S. anytime soon. A recent review of the snacks notes that they have a heavy lemon flavor that takes away a little from the taste.

“The first sensation, which I did not expect, was a very acidic bite,” wrote Impulse Buy writer Steve. “It tries to capture the citrus notes of Pepsi, but it’s over the top. Too lemony. The sweeter cola flavor is there but it’s subtler and overpowered by the intense citrus.”

The Cheetos don’t just have an unfamiliar flavor, they also fizz on the tongue like Pop Rocks, in order to simulate the feeling of Pepsi’s carbonation.

The snacks are just the latest in a long line of “Frankenstein foods”, which combine unexpected flavors and textures; this year we’ve seen the cronut, the Ramen burger, and the waffle taco from Taco Bell.

I can't believe this is a real thing: '#Pepsi-flavored #Cheetos not too wacky to sell': http://t.co/PddmP8Wv0Q
