Organisers have banned one very unusual item from Leeds and Reading Festivals this year.
The list of things not allowed inside includes fireworks and weapons, for obvious reasons, and one particularly peculiar thing.

People heading to the events will not be allowed to take pineapples inside with them.
Carrying the exotic fruit is a nod to Oxford band, Glass Animals, who will be performing this year.
Fans tens to take hundreds of pineapples along to gigs in tribute to the song Pork Soda, which includes the lyrics, "pineapples in my head".

And now, drummer Joe Seaward has suggested that it'll be a "challenge" for fans to get a pineapple inside.
He said: "Anyone who wasn't bringing a pineapple definitely is now.
"It's fruitist. Watermelons are fine, but not pineapples?"
The stage at Glastonbury was decorated with pineapples when the band played in June, and many fans attended dressed as the fruit.
Drones and glass are also banned from the festival.
A spokesman for Reading and Leeds Festivals told the BBC : "Organisers were a little concerned about hundreds of pineapples turning up on site so decided to ask fans not to bring them along."
The band reckon it'll be a challenge to get one in now
He added: "The tongue may be slightly in cheek on this one."
The list of items banned from the arena include:
- gas canisters
- animals - other than registered hearing or guide dogs
- items that may be considered as weapons
- paper lanterns
- fireworks or flares
- large bags (bigger than A4 size)
The festival runs in Reading and Leeds from August 25 to 27.
