I remember from my childhood the ring filling with water and there used to be a sea lion performance in the ring. And still fills with water .
''What to see at the Blackpool Tower Circus
Visitors to the Blackpool Tower Circus can expect a dynamic show that appeals to all ages. The circus offers a mix of traditional and modern performances, blending high-energy acrobatics, comedy and illusion. The show is hosted by the famous clowns, Mooky and Mr Boo, who bring a mix of humour and slapstick to the performance, ensuring that there’s something to entertain the whole family.
One of the unique features of the Blackpool Tower Circus is its water finale. At the end of each performance, the arena floor is lowered and filled with water, transforming the ring into a large pool. This sets the stage for a spectacular water-based performance, featuring synchronised swimming, diving and other aquatic acts that add a dramatic conclusion to the show.
The circus also includes a variety of acts from around the world, including aerialists, jugglers and tightrope walkers, all of whom showcase their skills in an environment that combines the intimacy of a traditional circus with the grandeur of a historic venue.''
I would try the local dive communities such as

I always remember the Lions roaring dawn chorus and the elephants in line trunk to tail going into the sea for their daily exercise and bath.
