Earmuffs were the headwear of choice at Forsyth Barr Stadium over the weekend, as thousands packed in to catch some rip-roaring monster truck action.
Two Hot Wheels Monster Truck Dunedin shows were held, featuring sized-up versions of the children’s toy.
Saturday’s show sold out with 16,000 people in the stadium, and another 10,000 attended yesterday’s show.
TEG Sport promoter representative Nathan Brown said there was plenty of entertainment on show.
"We delivered a crash, with Bec from the Big Foot truck flipping over, but she's OK."
"The truck's a little banged up but we're ready to go for a big second half."
The trucks were as loud as ever, although the stadium’s covered roof did increase reverberation, Mr Brown said.
The show probably set a record for the highest use of the sensory room — a space for children to take a break from the noise, he said.
"If you like a quiet night at the ballet, it’s probably not the show for you."
The best part was watching children’s reactions to the trucks, and parents’ reactions to their children, he said.
Kit, 3, and Mila Sparrow, 6, both of Dunedin, thought the monster truck doughnut competition, when the crash happened, was the best part so far.
Big Foot rolled on to its roof, which came off.
Driver Rebecca Schnell drove on after the truck was righted by a excavator.
Parent Kenzie Sparrow said the children had been looking forward to the show for a long time.
She thought Kit's upcoming birthday party theme might need to be changed to match his monster truck obsession.
Freddie Slipper, 2, of Mosgiel, was the proud new owner of a Tiger Shark toy, a mini version of the truck roaring around the stadium.
Grandfather Scott Klenner, also of Mosgiel, said the show was great, "loud and exciting".
"[It's] not the first intention with the stadium, I'm sure, but it's great to see," he said.
"And so many people, it's chocker."
