Pirates, pumpkins, and yo-ho-ho a bunch of candy is what you'll find at Pirates and Pumpkins this October at the St. Louis Aquarium at Union Station. Guest can test if they've got what it takes to join the pirate crew by walking the plank, digging for buried treasure and making their own pirate hats.

And of course, everyone will leave with their share of the candy loot!

Pirates and Pumpkins Trick or Treating will be held Friday and Saturday, October 17-18 and October 24-25 at the St. Louis Aquarium at Union Station from 5 to 7 p.m. (Last entry is at 6:15 p.m.)
