Furry antlers, Santa hats and Christmas jumpers were on display as pupils took part in a reindeer run to raise money for a life-saving defibrillator.
Youngsters at Fitzwilliam Primary School took part in the sponsored run in their playground on Friday.
Pupils raised £177.45 which will be used to buy a defibrillator for the school.
The issue gained national media attention after footballer Fabrice Muamba collapsed in 2012.
The former Bolton Wanderers player’s heart stopped for an hour after he suffered a cardiac arrest on live television in an FA Cup tie.
He made a full recovery, but at the expense of his football career.
Professional rugby league was also hit with a double tragedy when Wakefield Trinity Wildcats forward Adam Watene and promising young Morley prospect Leon Walker died while playing.
This encouraged Fitzwilliam Primary to fundraise and buy their own defibrillator. The easy-to-operate devices can be used by anyone in an emergency and display simple instructions.
They also have an intelligent automatic system that will only produce a shock when there is no detected heartbeat.
Fitzwilliam Primary School headteacher Susan Harrison said she was proud of the children for raising the money.
