A wordless Halloween joke as dependent as a radio script on written SOUND EFFECTS. Aunt Possum (per the title) and her unidentified tabby hear a WHOOSH, BANG as the door blows open, see two shoes (CLUMP, CLUMP) on the doorstep, a shirt hovering over (wavy FLAP-FLAP), a pumpkin atop the shirt (oooOOOooo). . . and a tell-tale fox tail protruding behind. So she goes after the ""ghost"" with a broom, and when the animal pranksters have been routed (WAH!), invites them in for a party. But tabby, casting a ghostly shadow behind the pumpkin, has a last laugh on them all. Feeble even for one run-through, with recycled Harrison Cady animals and not a jot of imagination.
