A white mouse has escaped from a laboratory having swallowed a very volatile explosive; when Jerry accidentally gets covered in shoe whitener, Tom mistakes his long-time adversary for the missing hazardous rodent—a fact that Jerry takes advantage of whenever possible!
For the most part, this is a fairly routine T&J cartoon that delivers predictable laughs, but there's one particular scene that qualifies this as absolutely unmissable for fans of the chaotic cat and mouse: Tom tries to stop a flat iron from landing on his face by blowing it back into the air with his mouth, the poor cat turning purple with the effort before the inevitable happens. Perfectly executed and absolutely hilarious, this easily ranks amongst my favourite T&J moments, making The Missing Mouse worth a rating of at least 7/10.
