[6] The game features seven levels which focus on Piglet entering his friends' dreams to help them with their problems.

Tigger is playable in Roo and Rabbit's dreams, and his level segments involve him having to sneak past Heffalumps and Woozles in order to stay out of their view range.

Pooh is playable in Owl and Tigger's dreams, and his level segments involve him having to run from Heffalumps and Woozles (after they heard his tummy rumbling) in order to be able to complete a task for Piglet.

The game starts with Piglet observing Pooh reaching for a beehive, Roo reaching for a ball that is caught in a tree, Owl trying to remember where his memory book is, Rabbit planting his carrots, Eeyore having his usual gloomy days, and Tigger painting his house to look like him.

After helping them all, the Hundred Acre Wood gets flooded and Piglet attempts to save his friends, who are trapped on islands with Heffalumps and Woozles.

He explains that the nightmares can teach him how to be brave, so Piglet leaves to find out how to do so while his friends begin to fall asleep.

After helping everyone, a flood covers the woods, forcing Piglet to face his fears rescue his friends while dealing with many enemies, and eventually the Granosorus.

"[9] Retrospective reviews of the GameCube and PlayStation 2 versions, made after the game's renewed interest in 2024, have been more positive.

"[10][11] 21 years after the game's quiet initial release, the GameCube and PlayStation 2 versions became a viral phenomenon online in November 2024, after a user on X (Twitter) shared a video that went viral showcasing the game's soundtrack and gameplay, and several YouTubers and social media influencers including Vinny Vinesauce compared the game's music, gameplay and visuals to the Resident Evil and Silent Hill survival horror franchises.
