Would it be wrong to have the turtle in that spot? And replace where turtle is now with tortoise. More importantly there's another missing spot, no slime, no legs, and 1 house. What goes there?

A landlord?

I GOT IT!! it's a softshell turtle!!

they live in freshwater like lakes so they are slimy, have 4 legs, and can retract into their body

A couple who make real-estate influencer videos?

That graph is also missing a data point at [Slime, Legs, House] = [No, 0, 1].

Nautiloids? They have a shell, are slimy, and have tentacles ("feet")

Four appendages, is slimy, and has a house...

Is it the average landlord?

Surinam Frog. 4 legs, slimy, and it incubates its eggs in the skin of the female's back for 4-6 months.

If we consider parasites as inhabitants, there are a lot of slimy house quadrupeds.

I guessing there might have been a https://en.wikipedia.org/wiki/Nautiloid, now extinct that had "only" 4 legs.

It's Longhorn Cowfish.

The hexagonal plate-like scales of these fish are fused together into a solid, triangular, box-like carapace, from which the fins and tail protrude.

a nautilus, as long as you accept tentacles as legs

Although, they have more than 4, so I guess they wouldint be featured at that particular point

1 house. 4 legs. Yes Slime.

A well lubeicated turtle

What about no legs, no slime, and a house?

A turtle with a cold?

I don't know, some turtles could be quite slimy. At the corner where it says turtle it should probably say tortoise, and at the "what goes here" corner you can put something like a softshell turtle.

Octopus, they typically go into objects and close them tightly like a shell, and no doubt about legs and slime.

I'm more concerned with the partials on the scale. 3 legs, maybe slime, and 0.25 house?

A middle class couple with a food fetish?

there's a hidden dot which has 1 House No Slime No Legs

It could be sea coral

I don't wanna meet anything that is slimy and has four legs. That is pretty much how games like half-life start.

As a turtle fan it's always cool when you can look at a diagram and suddenly spot a turtle on it! 🐢

It's like looking at the H-R diagram and going "ooo, Discworld would be right about there, possibly"
