It's worth keeping in mind that Clue #3 is three parts based on elements of a story, so not all the answers are in that one GIF. I think the key is figuring out which element each GIF in the set corresponds to and working from there.
One way to read elements of a story would be settings, characters, and conflict/plot. For example, this was my original guess from way back when:
Setting: Theme Park/Carnival (Whirly Dirly)
Characters: Killer Animatronic (There was a robot in one of the GIFs)
Plot: Trapped somewhere, and need to find a way to escape (Rick and Morty trapped in a jungle)
Or, you can read the elements of a story as beginning, middle, and end, which actually lines up with Oz.
Beginning: The Tornado (Whirly Dirly)
Middle: Trapped in a bizarre land, trying to find a way home(See above)
End: Reunited with the entire family at home (Robot GIF)
I definitely feel like there's something to the idea of a carnival setting, but the rest of the answer lies in the other two GIFs. I have no idea how undead carnies lines up with everything.
