M4A1-S | Party Animal was added to the game on January 21, 2026, as part of The Harlequin Collection, released with the Fourth Season update. The skin was created by Valve.
The skin uses a bright neon palette and imitates various animal prints. The barrel is predominantly purple. The handguard features a gradient transitioning from purple to blue. The lower receiver, pistol grip, and parts of the stock are finished in blue. The colors of these areas remain almost unchanged across different pattern indexes. The rest of the rifle is covered with a multicolored design featuring elements reminiscent of leopard spots, zebra stripes, and snakeskin. Their placement and color combinations depend on the pattern index.
The skin's Float Value ranges from 0.00 to 0.60, which makes M4A1-S | Party Animal available in all exterior conditions. The first minor abrasions appear on various parts of the rifle in Factory New condition and become clearly noticeable at approximately 0.10. As the Float Value rises, abrasions increase in number and size. At the highest wear levels, a significant part of the paint is worn away, and the animal pattern becomes almost unrecognizable.

Pattern #494 features a large area of blue leopard print, while #956 is distinguished by pink-and-purple leopard print. Patterns #111, #376, and #931 have a prominent purple design known as Purple Web. There are also variants dominated by orange leopard print, pink or orange zebra stripes, and a blue-and-pink snakeskin pattern.
