Checkout this quirky clip of a group of festival goers dressed up as dinosaurs causing havoc at British music festival, Boomtown.
Harrison Gwaspari, from Barnstaple, North Devon, UK, went to Boomtown with four friends and he thought it would make the weekend more fun if he and his group dressed up.
Attending with four friends and his cousin, the video shows them running around on the festival site, which takes place in Hampshire, UK and also having pretend fights.
They can also be seen dancing in their inflatable T-Rex costumes, and at one point a man can be seen riding on the back of one of them.
