We were called to a report of an inflatable trampoline apparently bursting on Gorleston beach, following a call to the ambulance service.
On Sunday, eyewitnesses and lifeboat crews tried to save the girl in Gorleston-on-Sea, who sustained multiple injuries, but she later died in hospital.
In an incident which started as fun and ended as a tragedy, a young girl died after a bouncy castle on a beach exploded.
The UK has been experiencing a heatwave in recent days, with temperatures in the Norfolk reaching 23 degrees Celsius on Sunday.
"We would like to thank everyone who rushed to respond to the young patient, and did everything possible to give her treatment and care".

The manager's come in with great ideas, the formation suits us perfectly. "We're not going to hide". It's a simple skill but it's about being able to perform it with pressure and everything around it.
The town's MP, Robert Halfon, has called for an "urgent investigation" into the regulation of the inflatables.
In a post on Facebook, she wrote: "Just seen the most horrific thing in my life.
Her family are obviously distressed, we can not imagine what they are going through and our specially trained officers are with them and will be with them for as long as they need them".
Halfon represents Harlow, Essex, where a 7-year-old girl, Summer Grant, was killed when a bouncy castle blew away at an Easter fair in 2016. A bouncy castle exploded at the beach and the child on it was catapulted about 20ft (6,1m) into the air.
A joint investigation into the death of the girl - who was visiting the beach with her family from Suffolk - has been launched by police and the Health and Safety Executive.
The couple, of Whitecross Road, Wilburton, near Ely, Cambridgeshire, were both found guilty of manslaughter by gross negligence and of a health and safety offence following the incident on March 26 2016.
