Share "local" headcanons related to very specific small aspects of pokemon, no setting/lore/universe bullshit (that includes pokeball bullshitscience).

I'll start. Leafon's greenery tail and ears are like hair or nails, they have no nerve endings and transition into actual "greens" you can cut without any side-effects (they will grow back). The greens you get are unique for each grass-type (i.e. they dont grow standalone) that has similar growths and are considered a delicacy.
