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?

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?

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")

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.

https://en.wikipedia.org/wiki/Nautilus with a lot of legs/limbs removed.

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

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

Is it the average landlord?

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.

1 house. 4 legs. Yes Slime.

Two married lawyers with a horse costume.

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

A well lubeicated turtle

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.

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

A turtle with a cold?

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?

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"

Crabs?

Someone who went home without cleaning themself off after getting slimed by Nickelodeon
