Themed swimming sessions will take place at local leisure centres during the school holidays.
Burntwood Leisure Centre and Friary Grange Leisure Centre will host the Finding Dory event in conjuction with the Amateur Swimming Society and Change4Life.
A trainer will be encouraging youngsters to dive like Dory, splash like sea lions and hide like Hank.
Councillor Andy Smith, Lichfield District Council’s Cabinet member for leisure and parks, said: “Linking Finding Dory with fun swimming pool sessions aimed at improving core aquatic skills is a great idea, and we’re delighted to offer them at our leisure centres.
“We hope plenty of people have a go and just keep moving this summer.”
The bookable sessions run from July 27 to September 4. For more details visit www.lichfielddc.gov.uk/holidayfun.
