Grab your little ghosts and goblins and fly by for a spook-tacular celebration presented by Susannah White’s Three Feet of Sunshine Guild. Come in costume for a hair-raising haunted house and enjoy pony rides, kids' tunes, ghoulish games and prizes, creepy crafts, pumpkin decorating, a costume contest and a parade. Plus, don't miss the Yummy Mummy Cupcake Walk and, of course, delicious Halloween Trophy Cupcakes! In celebration of our fifth annual Monster Bash, this year will feature two live performances by Caspar Babypants, at 4 and 5 p.m. Guests will also be treated to festive and reusable trick-or-treat totes. All proceeds from this fun event benefit Seattle Children's Pediatric Advanced Care Team. Bonus: Bring a new, unused costume for a Seattle Children's Hospital patient and receive an extra special trick-or-treat!
