When Bucky the Bear and Hillbilly Hare rent an Arcade-on-Wheels for a mysterious birthday party, they expect games and laughter-but instead, they're dragged back into the Void. With Ruckus the Raccoon rising as a dangerous new foe and the Void Keeper watching closer than ever, the crew must survive twisted neon trials, team up with alternate versions of themselves from the Bucky-verse, and uncover the truth behind the birthday no one dares talk about. The party isn't over-it's only just begun.
