It must be soap bubble fruit!

Soap 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 all the meaning 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 have been artificially bred, 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 its seeded parents (such as watermelons).

maybe soap bubble fruit is not a fruit at all? Obtaining it requires hunger and penance, and it only accepts people who are sincere and grateful. This is a bit like the "manna" that God gave to the Israelites in Exodus. The manna appears with dew, like frost, and has no distinguishing 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 is the soap bubble fruit so focused on being eaten? Aphids and scale insects do take care of diners and provide "easy to eat" honeydew. This is also to attract devout followers. Many ants form friendships with insects of Hemiptera. Aphids without ant companions will "squeeze" honey dew out and throw it away. Sugar-containing honey dew is very easy to breed mold, leaving it in its own place will pollute the environment. Aphids that take care of ants will slowly discharge honey dew, which has bristles at the end of its abdomen, so that honey dew drops can be hung on it, which is convenient 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.
