The Animal Courier in Dota 2 is a small, creature-based transport unit with a semi-realistic fantasy design. It features a compact, quadrupedal body with smooth, slightly textured fur or scales, depending on the variant, and is adorned with a saddlebag or pouch for carrying items. The courier's design includes expressive eyes and subtle animations to convey personality, with colors ranging from earthy browns and greens to more vibrant hues for special editions. Its proportions are balanced for readability in-game, with a slightly exaggerated head and limbs to enhance visibility.
