An RSPCA inspector was called to rescue 50 frogs who had been dumped in an Aldi car park in north London.
A passer-by found the army of amphibians jumping the car park in Kingsway, North Finchley at the weekend.
When an inspector arrived there more than 20 of the creatures hopping around loose, and another 30 in a tied-up plastic bag full of soil and algae.
The frogs were taken to the charity’s Putney Animal Hospital to be checked over, then later released back to the wild.
Anyone with any information about who may have left the frogs in this way should call the RSPCA on 0300 123 8018.
