Rubber Duck Frontier is a creature-collecting adventure set on the Pearlwater Isles. Players catch wild rubber ducks by drawing a bubble ring at the right moment, build a team and fight turn-based battles, including stadium team battles and a boss raid. Players can record their own voice for each duck they own. The game includes minigames such as voice-controlled parkour, duck bowling and a duck pond, and supports hosting or joining other players over a local network or the internet. A stream mode lets TikTok LIVE and Twitch viewers trigger in-game events through local webhook URLs compatible with tools such as TikFinity.
