A SHOP worker was given a surprise when she found a tiny frog, usually found in the Dominican Republic, hidden in a bunch of bananas in Tesco.

The tiny amphibian was spotted by a shop worker in Tesco in Hill Street in Blackburn, 4,200 miles away from its home country.

The shop worker then contact the RSCPA to collect it and took it to exotics rescue centre Reptilia in Ossett, who have named the frog Nana.

The tiny frog can usually be found hopping from tree to tree in the rainforest of the Dominican Republic

RSPCA animal collection officer John Greaves said: "The little tree frog was confined inside a bag of bananas so we asked her to make some tiny air holes in the plastic and add some water for moisture and keep him confined until we could attend.

“The amphibian must have had quite the shock when he emerged in a Lancashire supermarket considering he’s used to more tropical climates usually."

Mr Greaves took the frog to the a specialist exotics rescue centre in West Yorkshire to make sure the creature got the best care possible.

He said: "The staff there checked him over and identified him as a Dominican Republic tree frog.

“That means he’s definitely a long way from home - more than 4,200 miles in fact!

“He’s a little skinny following his ordeal but he should make a full recovery.”

It is expected the frog was hidden in the bananas as they were cut from the trees and was not seen until it was spotted by the shop worker in Blackburn.

Staff at Reptilia are currently taking care of the amphibian and said it will soon be up for adoption.

A spokesman for Reptilia said: "It's a Dominican tree frog.

"It's a bit underweight but it's doing fine apart from that.

"It will be looking for adoption in about six weeks time.

"Since it is was found in a bunch of bananas we have we've decided to name it Nana'."

A Tesco spokesman said: “As soon as our eagle-eyed colleague spotted our unfrogrettable friend, he hopped to it and contacted the RSPCA for help.

"We sell millions of bananas every week and our growers work hard to inspect our fruit carefully.

"However, given the freshness of our produce, this sort of thing can happen on very rare occasions.”
