A SCOTTISH zoo is challenging families to celebrate Halloween by carving creepy-crawly pumpkins to win free tickets.

Families who bring animal-themed carved pumpkins to RZSS Edinburgh Zoo will get a free child ticket (15 years and under) with every full paying adult, from Friday October 27 until Monday.

A selection of the best pumpkin designs brought in by visitors will be displayed in the zoo entrance until Halloween when all pumpkins received will be composted and used by to help fertilise plants in the park in future months.

Bruce Ritchie, head of business operations and visitor experience at RZSS Edinburgh Zoo, said: “This year we’re presenting a skin-crawling Halloweeen programme with the chance for visitors to meet Edinburgh Zoo’s most weird and wonderful animals.

The pumpkin challenge coincides with the zoo being invaded by Scotland’s most skin-crawling collection of insects, at the limited-edition Creepy Crawlies Exhibition.
