I remember people always questioned me as to what really made the two kinds of Slickers physically different other than poisonous/not poisonous.
The features are actually pretty distinguishable, if you were to happen upon them in the wild you’d be able to tell them apart pretty quickly based on their looks.
Poison Slickers are naturally slender, lithe long bodies. They are more flexible. Their heads are longer, ears point in towards each other and usually are longer. The bridge of their noses are longer helping pull their face down towards the chin. Their eyes seem to usually be more almond shaped and slanted. They rely on their sneakiness, posing and waiting for their prey to come too close to them… Ready to pounce in a flash!
Common Slickers are normally bigger. Sometimes twice as big as their poison cousins. Their faces are naturally more square/rectangular shapes. Shorter and perkier noses to pull in more scents. They are big hunters, they will hunt and chase down their prey so they developed bigger muscles to track, chase, and attack. Their ears are normally set outwards and are shorter while their large round eyes are sharp.
Differences between genders? Not much at all actually. You wouldn’t be able to tell the difference between a male and female unless you noticed their enlarged throat. Males can sing and croak to attract a females attention or get the attention of other slickers in the area. Normally Slickers chirp at each other.
If you ever wanted to quickly compare their personality to an animal imagine them acting like spastic Sphynx Cats!
