Thousands of children and teenagers donned their swimming costumers and old T-shirts to wallow in the brown sludge at Hines Park in Westland.
To create the muddy pit firefighters poured 100,000 litres of water on top of 200 tonnes of dirt. The result meant children spent hours diving, sliding and throwing sludge in the gigantic mud bath.
The fun included limbo contests and wheelbarrow races as well as the crowning of a mud king and queen – the winners were the messiest children. Wheel barrow races were no doubt more difficult in the squelch than on dry land and when they became tired from the exertion of moving through the sludge, many just wallowed, glad to lie down in the cool brown water.
Organiser Beverly Watts said: ‘Kids always have to stay clean at home. This is one day where they can get dirty.’ And it wasn't just the children having fun - the lure of the brown sludge was too much for some parents and they also got stuck into getting muddy, although they had to join the youngsters at the end to be hosed down by a firetruck.
Candi Bostain was one of the adult participants who took part. She said: ‘There’s nothing like the mud squishing between your toes. Now I know what pigs feel like.’
