Thanks for all the love from our sponsors – Guitar Hero for setting up multiple stations for our guests to rock out with the game all night long; Hasbro for providing an amazing pumpkin decorating room where partygoers used the DohVinci stylers to create awesome designs and for setting up the Nerf Zombie Strike station in our outdoor maze; Kraken Rum for helping us create the “Electrishock Mojito,” Jose Cuervo for providing the tequila for a “Manic Margarita,” and Freixenet for giving guests a delicious Spanish Cava to sip on; AQUAhydrate for keeping guests hydrated with water all night long; and Sprinkles Cupcakes for baking delicious mini cupcakes that fit to the theme with the pill-shaped design on top!

Another big thank you to our DJ Dominic Carter for spinning tunes that had guests dancing throughout the party and our three actors – Justin Valis, Jola Cora, and John-Jonne Smith – for getting into character as psych ward patients and scaring all the guests.
