This Japanese toymaker just brought back a 90s Easter egg.

Bandai has re-released Tamagotchi, the pocket-sized electronic pets that Millennials were crazy about when they were kids in the late 1990s.

More than 76 million of these low-tech digital eggs were sold worldwide, which owners kept “alive” by tapping buttons to feed and clean up after the 8-bit critters. The brand brought back the same egg-shaped design and 8-bit digital characters, but the 2017 versions have been scaled down to about half the size of the originals.

So far they’re only for sale in Japan for $13.55 (1,500 yen), and on Amazon Japan for $17.36.

But there’s plenty of other 90s throwbacks for the nostalgists out there. Like “Friends! The Musical!” opening off-Broadway this fall, from the parody masterminds behind other 90s-themed productions like “Bayside! The Musical!” and “90210! The Musical!” Song titles from the “Friends” spoof include, “The Only Coffee Shop in New York City,” “The Ballad of Fat Monica” and “We Were on a Break!”

“On the most simple level, nostalgia has been operating on a vague 20-year cycle for some time,” said Syracuse University professor and pop cultural historian Robert Thompson. “In the 1970s, we saw hit TV shows set in the 1950s; the 80s saw a resurgence in 60s culture; and the turn of the century brought new interest in 80s phenomena, from Alf to Mr. T.”

Plus, Millennials who grew up loving Bandai’s Tamagotchi will want to share them with their own kids.

Bandai also makes Saban’s “Mighty Morphin Power Rangers” toys, which are hotter than ever thanks to the new movie released last month that made $40.3 million domestic its opening weekend. And the rebooted super teens have inspired some pretty morphin’ fashion lines, including Dannijo’s line of lightning-bolt chokers and earrings for $98 to $148. Suki Waterhouse was spotted rocking a White Ranger hoodie from from streetwear brand KITH, and Gigi Hadid made headlines sporting a now sold-out $17 Pink Ranger beanie.

But back to speaking of pocket monsters, fellow hit 90s cartoon “Pokemon” returned big-time last summer with “Pokemon Go,” the mobile app that lets players hunt and hatch the mini monsters in the real world. The game made $206.5 million and was downloaded 100 million times in just the first month following its July 2016 debut. The license is also going strong with games including “Pokémon Sun and Moon” for the Nintendo DS.
