What "classic cartoon episode" trope would you have wanted to see if IJ got more seasons?

I'm talking like that quirky, classic stuff that's listed on TV Tropes. Like how the show has had a "fancy party" episode, a body swap/ "Freaky Friday", the high school reunion episode, even the "inside someone's mind" deal.

I would've loved to see some stuff about the paranormal- maybe if they had gotten the time for another Halloween episode? A classic "sick day in denial" is always good. Or, I know we've gone inside Reagan's mind, but this feels like the show that would do that sort of episode where the characters would get shrunken and poke around in one character's body lol
