Let's sort out the phenotypes.
There are 3 body types, 3 sides, 3 bottoms and 3x3 tops.
- Body type is blue, green (greenish), or brown.
The brown body is short, green and blue are long.
The greenish color could be meant as an intermediate between blue and brown.
- Side appendages are none, wings/leaves, or legs.
The number of legs reflects the body size, 3 or 4.
- The bottom appendages are none, one long or two short.
- The top appendage is a combination of two properties.
The general shape is none, single or triple.
The tips are also none, single pointed or triple.
There are 3 of each property.
What to do with it all?
It seems that each property can be absent. If we count brown as absent (it's shorter), then the rule for mineral, the left column, could be that only 2 properties are present.
Here is a possible criteria for the classification
Minerals have a majority of features absent, i.e. max of 2 visible features.
Vegetal features are: body: green, sides: leaves, bottom: single, top: triple, tips: triple.
Animal features are: body: blue, sides: legs, bottom: double, top: single, tips: single.
If there are 3 or more visible features: if there are more animal features than vegetal features, then it is an animal. If there are more or as many vegetal features as animal features, then it is a vegetal.
