Now frogs want the little mouse...or is it the snake?

Snake. Definitely snake.

true. Look how much it's drooling all over Nazrin

is it just me or does that slime look a little like its burning her skin?

it's more like the artist tried to work that shading like he did the tears, but used a different shade, probably to show a different thickness, and ended up looking like this.
hands', hair's, and nose's shading doesn't match up either
