A giant yellow rubber duck made a surprise entry in the middle of a harbor in Maine, United States. While nobody knows how and where it came from, everyone seems to be happy with its presence. The duck, which has the word ‘Joy’ stamped on it, is spreading happiness with its delightful appearance and the social media response is the proof.

Here is how the mystery duck looks like and the internet’s reaction to its sudden appearance.

While most Twitter users loved the duck and called its appearance their favourite news of the day, another user fears that the duck might have some spying devices installed in it. All in fair humour though!.

“Hopefully not equipped with Russian spy equipment. Lol Mysterious giant rubber duck appears in Maine harbor, wrote the user.

Coming back to the duck, the bright inflated toy appeared in Belfast Harbor over the weekend, and it’s still a mystery who put it there. It is 25-foot tall and so far hasn’t caused any inconvenience or posed any navigational issue.

Harbor Master Katherine Given told the Bangor Daily News that the duck doesn’t pose a navigational hazard, so there’s no rush to shoo it away and visitors are loving it, reported AP.

Given further told that the duck was first seen on Saturday and is there since then as it causes no hazard.

“Everybody loves it. I have no idea who owns it, but it kind of fits Belfast. A lot of people want to keep it here,” she told AP.

Another visitor by the name of Judy Herman, from Bala Cynwyd, Pennsylvania, loved the yellow ducky so much that she stopped to take photos on Tuesday.

“It’s wonderful. Who would expect to see a duck in the middle of the water here?” she told New England Cable News.
