Anapest Intrudes

In the dark of the night, on an All Hallows' Eve, as I lay down my head and got snugged in the bed, 'twas a shadow that bloomed, caused all senses to leave, as a huge hairy spider crawled, eyes gleaming red! Out in front, a large sack that she shuffled along, so I watched as she loped with that load full of gore, like the beat from a dirge or a horrid old song, da-duh-DUM, da-duh-DUM, as she moved 'cross the floor. Shaking hard, to the edge of the bed, silent crept; There she was, hairy legs, abdomen bulging fat. Sweaty palms, frazzled nerves, in the darkness I lept, closed my eyes, held my breath, threw my slipper - Kersplat! and as she scuttled off, protecting precious eggs, I wondered how she'd sound with two more dangling legs. --------------- for the All Hallows' Evening Poetry Contest sponsored by Craig Cornish written on 10/19/22 using anapestic tetrameter for the first 12 lines and iambic hexameter for the last 2 for effect (howmanysyllables.com incorrectly reports line 3 as 11 syllables due to the ')
