Londoners may have spotted some unusual wildlife in the UK capital as Fantastic Beasts: The Crimes of Grindelwald is released in cinemas, as LEGO Nifflers have been scurrying around the city.\r\n\r\nThe LEGO Group has released seven Nifflers onto the streets of London to celebrate the launch of Fantastic Beasts: The Crimes of Grindelwald, so those around the city should zip up their purses and button down their wallets if anything shiny resides inside. There have also been sightings in Edinburgh and Cardiff.\r\n\r\nNifflers are native to Britain, as magizoologist Newt Scamander documented in his book, and are drawn to shiny items. These 11,000 brick critters have visited the diamond district Hatton Garden, the Tower of London \u2013 presumably for the Crown Jewels, before finding their way, appropriately, to the LEGO Store Leicester Square.\r\n\r\nLEGO Harry Potter 40289 Diagon Alley is currently available free with any order from shop.LEGO.com totaling \u00a380 or more. Sets available include 75951 Grindelwald\u2019s Escape and 75952 Newt\u2019s Case of Magical Creatures based on the Fantastic Beasts films.\r\n\r\n\u201cWe wanted to inject some LEGO magic into the hearts of Wizarding World fans across the country, and what better way to celebrate the creativity and fun of LEGO bricks than to create mischievous Nifflers in brick form,\u201d said Rory Unwin, Brand Manager for LEGO Wizarding World. \u201cThe reaction from the public has been fantastic, up and down the country \u2013 and we hope Wizarding World fans enjoy seeing them as much as we did building them!\u201d\r\n\r\nA double VIP points promotion is currently applied to 71043 Hogwarts Castle, meaning fans buying the set get 10% to spend at shop.LEGO.com at a later date.\r\n\r\nLEGO Harry Potter sets are available now from shop.LEGO.com.\u00a0Fantastic Beasts: The Crimes of Grindelwald is in cinemas now.
