Hertfordshire's Paradise Wildlife Park features in the latest video from YouTube sensations the Sidemen, after the group filmed a Hide and Seek at the popular attraction.
The seven-man group, which includes Prime drinks founder KSI, explored the zoo and its more than 800 animals as they searched for places to hide.
With Harry Lewis, also known as Wroetoshaw, quickly finding his fellow stars - which included guests Chris MD and Danny Aarons - KSI and Behzinga battled it out for victory.
The video, which was uploaded to the Sidemen's 18.7 million subscribers on Sunday evening, already has 2.5 million views.
The video ends with the group being given the chance to feed Paradise's camels, as well as nervously passing food to the park's Amur tigers, with guidance from the zoo's section lead of large carnivores.
"It was a pleasure to welcome the entire Sidemen group and they were incredibly respectful and willing to learn about the animals whilst filming a fantastic video," said a Paradise Wildlife Park spokesperson.
The YouTube stars are also seen visiting the zoo’s newest additions of the baby capybaras, feeding the Bactrian camels and being visibly shocked by the conservation statistics of some animals' numbers in the wild.
This collaboration between a zoo working to share the wonder of wildlife and educate visitors about the importance of species and habitat conservation with a YouTube group with over 18.7 million YouTube subscribers is "the boldest collaboration yet".
It is hoped that this will allow the younger generation to learn about the protection and conservation of animals in a new and engaging way.
