One of the most wonderful things about Imaginary Friends is that they can literally be anything their creator wants! While Foster’s Home has always been a welcoming place for those Imaginary Friends that would otherwise be forgotten, one fact that has been lost to time is that the Mansion that makes up Foster’s Home itself, is in fact an imaginary friend!
Though it was allowed to slumber for decades, a certain event has awoken it! And now that it's alive and awake once more, it has remembered its true purpose. This Mansion wasn’t supposed to be an imagined mansion, it was supposed to be a Playboy Bunny Mansion! Help the house realise its horny dream of becoming a lewd mansion! And what does every Playboy Bunny Mansion need? A bunny! Which makes Frankie its main target as she’s led down a path of corruption.​
