The 'One Thing' hit makers - comprising Niall Horan, Louis Tomlinson, Niall Horan, Liam Payne and Zayn Malik - often receive bizarre gifts from their devoted fans.
Asked the weirdest things they have received, Harry said: "A box of mushrooms dressed like us."
Meanwhile, Louis was given an unusual pet by a fan and another wanted Liam to ensure he was well protected.
Louis said: "[The weirdest gift I've been given] was a live hermit crab."
