This is the amusing moment a group of giraffes sparked chaos as they reached inside a safari park bus for snacks.

Footage shows holidaymakers feeding carrots to long-necked mammals as they poke their heads through the vehicle's windows in Kanchanaburi, Thailand.

One tourist can be seen handing a piece of the vegetable from a bucket to a giraffe on December 8.

Moments later, the ravenous creature thrust its long neck further into the bus, lunging for the entire bowl of carrots.

The visitors became terrified as several other giraffes poked their heads in to search for more treats, prompting the group to scream and scramble away from the animals inside the vehicle.

Despite the chaotic encounter, the group managed to feed the giraffes all the carrots the zoo had prepared for them.

Giraffes tend to be calm and curious, often observing humans from a distance. They can be quite gentle when they approach humans, especially in controlled environments like zoos or safari parks.
