It's Epossumondas's birthday, so Mama's whipping up his favorite biscuits. But she's plumb out of sody sallyraytus! (That's baking soda to all you Yankees.) Everybody knows you can't make big, fluffy biscuits without sody. One by one, Baby Gator, Auntie, and Mama scoot to the store to fetch some. But when no one comes back, it's up to Epossumondas to run out and see what's what—until he runs smack into a great, huge, ugly Louisiana snapping turtle!
