What is in an under-the-sea package?
An under-the-sea theme turns a room into an ocean: mermaids at the entrance, jellyfish and octopus characters roaming the crowd, aerial acts overhead and a sea god with a fire trident for the finale.
It is one of the most photographed themes we offer and works for summer parties, product launches, charity galas and pool parties.
