In the Monster Tutorial for Project: Playtime, it is divulged that Huggy Wuggy plays a vital role as one of the selected toys assigned by The Prototype to provide sustenance to the smaller, more vulnerable experiments such as the Wuggies. These unfortunate creatures are fed with the remains of the Resource Extraction Specialists, employees hired by Leith Pierre, who have been sent into the monster-infested factory and its attractions in an ill-fated attempt to revive the Bigger Bodies Initiative. In Log 08502, Huggy was briefly mentioned as Experiment 1170, and was dubbed the most optimal subject, as he possesses the ideal amount of intelligence and is obedient to the scientists working at the company. This however can be proven as false, as three different entities can be depicted talking to us throughout the Vent Chase via the conveyor walls. Isle of Man, Isle of Wight, Northern Ireland and the Scottish Highlands) may take longer to reach you.

In Chapter 1: A Tight Squeeze, Huggy strictly adheres to the objectives given by The Prototype. His task is to surveil and protect the Playtime Co. Factory, alerting others to the presence of any new intruders. Huggy takes a stealthy approach, stealthily stalking the player until finally confronting them with a lethal embrace. This is evident by the fact that some writings say "Starving" and "I'm so hungry." Further proven by the fact that he seems to eat you when you die.Huggy Wuggy is presumed to be the one who wrote the countless words within the walls during the Vent Chase. According to Micah Preciado, Huggy Wuggy was not actually inspired by any animal like a dog. Instead, he was unironically inspired by Sour Patch Kids [2]. Huggy Wuggy, otherwise known as Experiment-1170, is a toy produced by Playtime Co., who makes his titular debut in Chapter 1: A Tight Squeeze. As stated by Playtime Co., Huggy is one of their most successful products. Whilst we will do everything we can to meet the delivery times above, there may be factors outside of our control and we cannot guarantee delivery within this time frame. While walking, Huggy has a stiff, yet rather lithe and oddly organic-looking gait. He is capable of breaking into incredible bursts of speed, using his long arms and legs to propel himself forward. While crawling through the vents after the player, Huggy is able to bend and contort his body to fit into tight spaces. Before the player drops the crate onto Huggy on the catwalk, he can be seen sprinting towards the player on all fours, much like an ape. Due to his sheer height of a whopping 18 feet tall, he possesses a size advantage against average humans. During the vent chase, Huggy is able to cut off and keep up with the player by navigating through the ventilation system.

After managing to momentarily escape Huggy and landing on a brittle catwalk, the player pulls a crate onto the crumbling structure just as Huggy bursts from the vents, causing it to collapse. Though the player manages to land safely on another catwalk not far below, Huggy strikes the railing and proceeds to fall into the abyss on the facility, slamming into several pipelines and leaving behind dark red blood splatters. However, this has been proven false, as it turns out the eyes assumed to have been viewed as a reflection of the floor.In a trailer headshot close-up of Huggy, it seemed that behind his plastic "eyes" lie big shot, human-like eyes. Huggy Wuggy was initially introduced in Chapter 1 as a statue in the Main Lobby of the factory. However, once the player restores power to the entire facility, Huggy Wuggy mysteriously disappears. Throughout the chapter, Huggy Wuggy makes occasional, brief appearances until he finally reveals himself and starts chasing the player during the intense Ventilation Chase sequence. Towards the end of the chapter, he is witnessed plummeting deep into the depths of the Playtime Co. Factory. Originally marketed as a toy intended solely for providing platonic love through hugging, Huggy Wuggy was designed to possess warm and appreciative qualities.

His monster counterpart remains largely the same, with the exception of his eyes being dilated bigger than intended, giving off a deranged and disturbing physique. Behind his lips is a maw of dozens of jagged needle-like teeth. Closer observation of Huggy's mouth shows a secondary set of jaws located by his throat, akin to that of a Moray Eel.
