Batman and Robin, the Little Mermaid and (most importantly) Santa Claus were spotted heading for the icy water all in the name of charity.
Little Mix's Jade Thirwall, who celebrates her birthday on Boxing Day, X Factor winner Joe McElderry and Paralympic gold medallist Josef Craig were among the hundreds of people down on the coast doing their bit.
