Peter Hodge, the Sussex beetle recorder has asked the following:
"About 1/2 hour ago (5.30pm) I discovered a young Common Frog perched on the porcelain rim of our downstairs toilet. The only way it could possibly have got there is by swimming up through the sewer.
Is this something that frogs are known to do? If it is then it goes a long way to explaining why frogs sometimes turn up in places where there are no ponds or freshwater."
Does anyone know the answer?
