It was a case of anger.
According to news.com.au, a kangaroo was caught on video slapping an Australian man in the face while trying to protect his kids from the jumping mad marsupial.
The terrifying attack took place on Christmas Day in South West Rocks, where Mitchell Robinson tried to scare away the animal that was hanging around and digging holes in his property.
The kangaroo jumped at the man and knocked him to the ground before escaping.
Family friend Tina Grace Rowe told a news channel Down Under that you could see the attack coming.
“It just stared at him and he took something to try to scare it away and as soon as he did you could just see it going to him,” Rowe told 7NEWS.
‘It was huge. He was a big male kangaroo – big box, ”she added.
Robinson, who already had a broken arm, luckily escaped with just a scratch, the station said.
