refs for TWO of my silly splatoon ocs!! im gonna get to the other two that were in the comic soon lol

to fit the role of words like plant, animal, fungus, broad categories of life forms with no relation to earth-native ones

first idea:
Horticulum (pl. Horticula)
from latin Hortus (garden, same root as horticulture) and diminutive suffix -culum
literally Small Garden

to refer to plant-like colonial organisms, perhaps, or mid-sized rooted structures like mycelial colonies or the entangled roots of large groves of trees like that one giant clone-forest
