To commemorate the release of Fantastic Beasts: Crimes of Grindelwald, Warner Bros. has unleashed Nifflers throughout the U.K. in an apparent Wizarding invasion, courtesy of LEGO.

According to Gizmodo UK, Newt Scamander's platypus-faced allies were seen all over the streets of London, with coins in hand and pearls around their necks. There are at least seven Nifflers on the loose in London, with most strategically placed around the city's shiniest attractions and most valuable possessions. Nifflers were spotted in Hatton Garden's diamond district, at the Tower of London in search of the Crown Jewels and, finally, in Leicester Square by the LEGO Store. The creatures didn't just stick to London, as there were also some found in Cardiff and Edinburgh.

"We wanted to inject some LEGO magic into the hearts of Wizarding World fans across the country," said LEGO Wizarding World Brand Manager Rory Unwin, "and what better way to celebrate the creativity and fun of LEGO bricks than to create mischievous Nifflers in brick form? The reaction from the public has been fantastic, up and down the country – and we hope Wizarding World fans enjoy seeing them as much as we did building them!"
