A Grabpack test [YARNABY UPDATE!]

A Grabpack test [YARNABY UPDATE!] is a fan-made puzzle and physics sandbox on Roblox developed by a four-person team - Elian3103, Enryprew_br, Rixxles, and Maki - recreating the Grabpack mechanics from the Poppy Playtime horror franchise. Players use a dual-handed device with independently controllable left and right extending hands to grab surfaces, fling objects, and interact with environments in the style of the source game. Launched in July 2025, it reached 132 million visits by April 2026, driven by the enduring popularity of the Poppy Playtime IP on Roblox.

The Grabpack is the entire mechanical identity of the game. Left Click fires the left hand and Right Click fires the right hand - each shoots independently and can latch onto objects and surfaces to swing, pull, or interact with puzzle elements. The Hand Wheel (Q key) switches between hand variants or modes, while a flashlight (F key) handles navigation in darker horror-themed areas. Up to 8 players share each server, making it an intimate co-op sandbox rather than a large-scale competitive game:

• 🗺️ Grabpack mechanics - fire each hand independently to grab surfaces, objects, and interact with puzzle elements in the Poppy Playtime style
• ⚔️ Yarnaby Update content - new environments and encounters themed around Yarnaby, the ball-like antagonist from Poppy Playtime Chapter 3
• 🎭 Co-op sandbox - up to 8 players per server explore and experiment with the Grabpack system together in small-group sessions
• 💎 Troll Hand - a premium gamepass (119R$) providing a hand capable of flinging other players, adding a social chaos layer to the puzzle sandbox

The keybind layout mirrors the Poppy Playtime PC game directly, making it a familiar experience for fans of the source franchise. The developers explicitly warn that decompiled copies and unauthorized republications exist on the platform - this is the original, and the clone problem is severe enough to be stated in the official game description.

A Grabpack test [YARNABY UPDATE!] is the center of Roblox's Poppy Playtime fan game ecosystem, drawing traffic spikes with each new chapter and character release from the franchise.
