Speaking to MS News, the person who filmed the encounter, Bernice, 43, said she first noticed something unusual from a distance.

Tortoise appeared to be laying eggs
Bernice told MS News that she noticed the tortoise shortly after spotting the lizard.
“The tortoise seemed like it was laying eggs or about to lay eggs,” she said.
This prompted her to begin recording the interaction, as the situation appeared potentially dangerous for the tortoise.
Bernice said she was standing around five to 10 metres away from the animals while filming, while “another man with a white furry dog” was in close vicinity.
She added that no rangers were present at the time.
“It’s just a park connector, and it’s quite common to see monitor lizards in Sengkang.”

“From the comments, it seemed that many were expecting that maybe the tortoise was going to be attacked.”

‘Reminds me to be careful in nature’
What stood out for Bernice was the size of the monitor lizard, claiming it was the biggest she had encountered.
She added that witnessing the interaction up close was a reminder of how capable wildlife can be.
“To watch it in person, seeing how the monitor lizard travels from far and then approaches the turtle further reminds me to be careful with animals,” she said.
“They are more skilled than humans in so many ways.”
