Synopsis:
Mxyzptlk returns disguised as a leprechaun. He creates his usual mischief by pestering Jimmy Olsen, as Casey O’Rourke. Since neither Jimmy or Superman know that O’Rourke is the 5th dimensional imp, they can not trick him back to his own world.

Mxyzptlk does speak his name aloud in front of a talking parrot, which speaks backwards. The parrot repeats Kltpzyxm over and over, but it is actually an eyechart in Jimmy’s trophy collection which Mxyzptlk reads that sends him home to his own dimension.
