The first sentence saying "this giant fruit" and the first image lead me to believe that it's big enough to fill a room. That was pretty confusing for a minute.
It's big as a watermelon, but with a different shape. Their trees are tall, what makes dangerous to stay under them due to risk of the jackfruit falling over you.
But the picture accidentally makes use of forced perspective to make the fruit appear as though it's on a hardwood floor in an otherwise empty room, which it dominates.
