How Cooler Fusion Works

Your catches go into the cooler, which also handles fish fusion. The opening fusion steps use these quantities:

• 10 fish → Shiny
• 8 Shiny → Gold

Use those requirements to track your next fusion target in the cooler.

Auto Fuse costs 199 Robux. It automatically fuses a stack once it contains enough fish, then continues through higher fusion steps as enough eligible fish accumulate. Its purchase buys automation for that process.

Match the pass to the task you want it to handle: Mutation Hunter increases mutation chance, while Auto Fuse manages eligible stacks in the cooler. Review your stored fish and showcase income before deciding which upgrade serves your current goal.
