South London Swimming Club (SLSC) have swapped the lido for the stage.
Swinderealla tells the tale of a Tooting Bec Lido legend who is attempting to get a place on the swimming team for the 2016 Olympics.
But her mean colleagues try to stop her, while she wonders whether she will ever find true love.
There will also be a performance from the Dive-in Belles, the lido's own synchronised swimming team and the Lido Allstars.
Lido ducks and geese will also be creating antics.
The event marks the launch of the new SLSC Benevolent Fund.
All proceeds from the panto go to the fund, which will help members disadvantaged by health or financial difficulties to access the lido.
Visitors will be able to tuck into homemade cakes, tea, drinks from the bar.
There will also be a raffle with the chance to win prizes.
Swimderella, St Boniface Community Centre, Mitcham Road, Tooting, March 1, Doors 2pm and 7pm, tickets adults £10, children £5, cons £7.50, visit slsc.org.uk or call 020 8871 7198
