We're turning it on with FREE face painting, bouncy castle, arts and crafts, large games, Tip top ice blocks, Whittaker's chocolate treats and live music. PLUS look out for your chance to meet and grab a photo with Moana, Elsa, Batman or Pirate Davy Squidcheese.
There's extra keeper talks throughout the day and you might even get the chance to go behind the scenes!
The Mama's Donuts team will be here, visit The Hungry Morepork team for delicious spud sticks or head to the The Breeze Sweet Stations for some sweet treats for the kids.
And we're celebrating 50 years, so we've got 50 spot prizes to be won throughout the day as well as anniversary treats, while stocks last.
Something for everyone - see you there!
