Aphid

Aphids are friendly mobs that appear in temperate biomes and often cling to plants.
It is a very small size and has very low physical strength.
This mob grows a little when it clings to the plant.
However, even if you grow up, your physical strength does not change.
And this mob is mainly attacked by spiders as food for spiders.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
