Fsr I wanted to finally design that elemental tail rat thing from the kel & alex story
I went a little deep and started considering the biology of it
what look like whiskers are actually gills since the end of it's tail can transform into water
whilst on the topic of the tail, even though it's fire resistant, some of the species are known to have slight charring which is sometimes a sign of age or some slight scar of failures in younger years to control flames produced from the tail
there's more but that's for later
