Those using walking poles in the Lake District may have encountered a strange blob-like substance on the fells in the past few days.
Walkers around the Patterdale Fells have noticed some of the strange white translucent globules, slightly reminiscent of the 1958 horror film The Blob, in which the jelly consumes every living creature it encounters, growing in size with each meal.
Expert Dr Hans Sluiman from the Royal Botanic Garden in Edinburgh noted that the mysterious goo has appeared before and he studied samples found in Scotland two years ago.
He stated. "I did discover that the jelly is made up almost entirely of water, but was not able to find out exactly what it was."
Dr Sluiman said one possibility was that some creatures had eaten "toxic frogs" and spat them out while half-digested, but noted nobody can be sure.
The Patterdale area contains popular fells such as Helvellyn, High Street and Place Fell.
