A white German pet shepherd Gypsy gave birth to a lime green puppy in North Carolina recently.
The green coloured puppy was named "Hulk" after the fictional superhero similar to the same hue, reports NDTV.
"I started freaking out," the owner Shana Stamey said. "But everybody was healthy. Gypsy gave birth to litter eight puppies among them Hulk took the Internet's attention," he added.
Despite his neon green hue, the puppy is perfectly healthy and there's an explanation for his green colour.
"The sack that they're in when they're in their mom, there can be meconium in there and that tends to stain them," Junaluska Animal Hospital veterinarian technician Suzanne Cianciulli explained to WLOS. Meconium is an infant mammal's earliest stool. It tends to stain white fur, explained Ms Cianciulli.
A picture of the lime green puppy was posted by Chris Grigg with the caption: "Our German Shepherd graced us with a 'Green' pup, 'Hulk' is 5 days old!" Hulk's unusual colouring has also left Twitter users amazed.
Hulk's green fur will gradually fade to white. According to WLOS, Shana Stamey and her family plan on getting Hulk adopted when he is old enough. They consider themselves lucky to have Hulk.
"A good luck charm. We think so. He's pretty special," Ms Stamey said.
