To find out all about the craze, they had the CEO of Headstart International Andrew Hendy on for a chat - and he announced The Morning Show hosts Larry Emdur and Kylie Gillies would have an Ooshie created in their likeness.
Now, after two months and nine days, the hosts have come face-to-face with their mini, squishy selves - and with only one each in existence, they're officially the rarest Ooshies in the world.
"They will be the only ones available in the world," the CEO claimed in August... and he kept his word!
This morning, the one of a kind Larry and Kylie Ooshies were presented on the show.
"They've arrived in all their miniature glory!" exclaimed Kylie.
They even come with their personalised initials on the back of their capes.
"Ooshie people, thank you for being so generous in the hair stakes," Larry joked, claiming his Ooshie gave him more hair than reality.
Before these unique Ooshies were created, the rarest was the fuzzy Mufasa Lion from The Lion King collection.
There was only a handful of those... but these are the only two Larry and Kylie Oosies, putting them in the top spot as the rarest.
