More than 20,000 people gathered in Bunol, Spain, to throw 130 tons of rotten tomatoes at one another on Wednesday.

The "La Tomatina" festival is a 75-year tradition for the city, but it was forced to halt the practice for the past two years due to COVID-19. Photos show party-goers covered head-to-toe in mashed tomatoes, with many of them having the foresight to wear goggles.

The truckloads of rotten and otherwise undesirable fruit started arriving at midday, and attendees launched them at one another for more than an hour, according to Reuters.

The festival's origins are murky, but tradition says a similar fight spontaneously broke out between residents in 1945.
