Your child will love a marine themed birthday party at the Anglesey Sea Zoo. We have a choice of two menus available and each party goer leaves with a party Pirates Chest. The price includes a fishy chocolate birthday cake (normally not actually made with fish), use of the party room, and of course, access to the aquarium and the play area outside, including the huge Octojump bouncy castle!
