To make these special pears, a plastic mold is placed around the fruit when it is very small and young and still on the tree. As the pears grow, they fill the Buddha-shaped mold, making them look like small statues. Once the molds are completely filled, the molds are removed from the fruit and they continue to grow freely. By the time the pears ripen, they look just like Buddha.
I was wondering if they used molds
I actually did cubed tomatoes. If anybody wants to try them out. I have the 3d print files for public use (cc by sa).

Good that they are not using mold.
