Youngsters got spooky to help sufferers of a rare genetic disorder.
The children, who are pupils at Marsh-based Huddersfield Grammar School, helped organise a charity Halloween party.
The fun event raised £300 for Smith-Magenis Syndrome (SMS).
The condition is caused by an abnormality in chromosome 17 and affects only one in 25,000 people.
The party was organised by Lilly and Freddie Beaumont, aged five and three from Lepton.
Their 21-year-old cousin Cassie Arnold has SMS.
The children’s friends Molly, five, Brooke, 11, and Daisy, 11, all from Lindley, also helped with activities for the event.
These included a scary dip, creepy cards and a find the stolen treasure game.
Kelly Beaumont, Lilly and Freddie’s mum, said: “I am very proud of them all as they helped decorate the room, run stalls, sell tickets and put their time into making sure everyone was having a good time.
“The parents and children from Huddersfield Grammar School helped support this event by coming along and generously donating gifts for the raffle.
“The charity is very close to our hearts as Cassie is an amazing part of our family.”
The friends hope to run another similar event next year. At school they were presented with a certificate of thanks for their hard work.
