Whats the trope called where someone zooms off so hastily that they leave behind something like a dust cloud, their eyes, etc.
like in the Spongebob episode Pranks a Lot where a guy runs off and leaves his eyes behind (and then the eyes subsequently scream and run off on their own)
or the subversion in Phineas and Ferb episode Does This Duckbill Make Me Look Fat where Doofenshmirtz runs off leaving a cloud of dust, only for the dust to clear and reveal that… he left himself behind, so he didn’t move anywhere
