We only know of one, thanks to Green.
HTF amnesia
a world where a infection is spreading, & Flippy & Flaky have to stop it (P.S. I just got a message from Green saying that Flaky is dead. so it's up to Flippy now.)
Of course there is more details to the world. but Green has to send in more information about it. Also a secret universe is one that is hidden from the other universes. The void decided to hide it for some reason.
