On the way home tonight, I thought of "turtles explode, when jumped on, rather than leaving a shell to kick", and thought it was perfect, because it wasn't wordy and was unambiguous. But I just now realized that that wording doesn't have the "shortly after" in there, so it sounds like they'd explode the instant they're jumped on.
I LOOOOOOVE Flying Omelette!!
