English Art/Literary Poetry & Literature

Let's imagine a child watching a film / cartoon they know very well. Now, the child knows exactly what's going to happen before it actually does. What would be the most natural phase they would use in the gaps below
[....] accident (meaning - an accident is just going to happen)
[....] naughty cars (meaning - naughty cars will show up in a minute)
[....] harvester (meaning - a combine harvester will appear)
I am sure there are many ways to fill the gap, but what I'm looking for is someting universal, a fixed phrase (does not have to be really grammatical) used by kids, children spontaneously.
To use a metaphore from real life, something similar to the Phonics Bus - you push a button and the voice goes:
xxx says yyy (dog says bow, wow; cat says meow). This is simple, childspeak English, and the phrase 'says' remains constant - so what similar phrase would a child use to preempt a scene in a film?
