Apparently there’s an Indian actor named Cactus.
Here’s the evidence for this hypothesis, an article in the Times of India.
Actor Sabyasachi Chakraborty, who is also a part of the video along with Prosenjit Chatterjee, Antara Chowdhury, Cactus and others, says, “As human beings, it is our duty to help them.
So Cactus is not just the name, but the name of a “human being”.
Here’s the photo.
I hope Cactus is the one in the middle.
