The spooktacular Children’s Zoo shows featuring live animals returns this year at 6 and 7 p.m. nightly, with an additional 8 p.m. show on Fridays and Saturdays.
Please note, these are the only animal exhibits open at night during the event.
Eerily draped in cobwebs, the Conservation Carousel will be transformed to the not-so-spooky "Scare-ou-sel." (Additional fee $3/person. Note: Anywhere Plus Passes are valid at this event.)
Visit the 4-D Theater for a showing of “Dracula 4-D!” On holiday in Transylvania, teenager Kevin and his bumbling dad accidentally awake the undead vampire Dracula! (Additional fee $5/person.)
Gather 'round the fire as storytellers like Terry Rantula spin wild tales about snakes, spiders and bats. Perhaps Grandmother Goose will share chronicles of other critters. Come wag your wild tails, gaze with your glowing eyes and perk up your listening ears as captivating animal stories are shared.
