Soap bubble fruit is a strange thing. Because it doesn't grow from any plant and has no anatomical structure, it looks like a bubble. It seems that the whole point of its existence is to be eaten. The reason why plants produce fruits is to attract animals to feed and spread seeds. The fruits we see today are artificially cultivated, and their volume and taste have been greatly improved.

Soap-soaked fruit has no seeds, which is equivalent to losing the goal of fruit existence and the goal of all biological adaptors-reproduction. We cultivate seedless fruits artificially, either by grafting or cutting (such as grapes and oranges) or by their seeded parents (such as watermelons).

Maybe soap bubble fruit is not fruit at all? It takes hunger and penance to get it, and it only accepts sincere and grateful people. This is a bit like the "manna" that God gave to Israel in Exodus. Mana appears with dew, like frost, and has no obvious biological characteristics. The whole meaning of its existence is to be eaten, because it is a gift from the gods, not a product of biological evolution.

Why soap bubble fruit pays so much attention to being eaten. Aphids and scale insects do take care of diners and provide "easy to eat" honeydew. This is also to attract devout believers. Many ants form friendships with Hemiptera insects. Aphids without ant companions will "squeeze out" honey dew and throw it away. Sugar-containing honey dew is very easy to breed mold, and leaving it in its own place will pollute the environment. Aphids who take care of ants will slowly discharge honey dew, which has bristles at the end of its abdomen, so that it can be dripped on it for ants to drink. If the ant can't come in a short time, it will even suck the honey dew back into the body and provide it later.
