A supermarket in Thailand got a "giant" customer Tuesday. Shoppers were in shock when they spotted a huge lizard scaling a shelf inside the shop.

A video of it has gone viral on social media, receiving thousands of likes and comments. The footage shows a water monitor lizard, roughly 1.8 meters long, climbing up a shelf inside a 7 Eleven store, while toppling the merchandise stacked there.

In the background, people can be heard screaming and laughing, but the chaos does not deter the reptile. It continues to climb to the top before pausing to rest, seemingly enjoying the warmth from the neon lights overhead.

The nearly one-minute-long video was captured by a customer Tuesday in the Nakhon Pathom area of Thailand, said a report by Global Times. The customer also paused for a selfie with the reptile in the background. No one was reportedly hurt in the incident.

The video received some interesting reactions on social media. A person who shared the clip on Twitter said the lizard might be in search of food as most restaurants and street food stands remained closed. The dry weather with little rain may have left it hungry, she commented.

"Am I going completely mad or is there a cat behind it?" one user commented, while another saw the humorous side and wrote, "Now someone needs to add the Godzilla theme to that video...".

After a shop assistant alerted the police, handlers turned up at the shop, tranquilized the animal and released it in a nearby forest area, the report said.

Last month, another video of a monitor lizard inside a toilet in Singapore had gone viral online. Authorities cordoned off the toilet area to help the lizard make its way out.

Water monitors are one of the most common monitor lizards found throughout Asia. These creatures are muscular, with long, powerful laterally compressed tails.

In Thailand, "hia," the local word for a water monitor, is used as an insult and some believe the animal's name can bring bad luck.

They are carnivorous and eat fish, frogs, rodents, birds, crabs and snakes. Though monitor lizards generally avoid humans, they deliver a nasty, bacteria-filled bite when threatened.
