Grintale is a Pal resembling a massive, bulky cat with a split tail. Its medium-length fur is of a dusty purple complexion throughout most of the body, including the head, enormous triangular ears, and back. Underneath this thick layer of purple fur are two more layers; a beige-coloured middle layer that encompasses the face, legs, and sides, and a black-coloured inner layer that covers the underside. The tail is black and cable-thin compared to the rest of the creature, and bears a purple band just before where the tail splits into two.

Its face is its most distinguishing feature, with a pair of giant, circle-shaped, glowing yellow eyes with white pupils, and of course, fitting of its name, a big wide grin underneath, full of comically big, triangular teeth.

It is much bigger than the player character, at roughly 200-210 cm at the head, not including the ears (assuming the player avatar is around 180 cm).
