Choose a fusion target
Choose a fusion target, then open the canonical planner to calculate next-rarity output and remainder. This calculator keeps the math explicit and leaves hidden odds, live boosts, and economy rates unclaimed.
Collect All Pets Calculator
Plan a Collect All Pets session around the verified hatch, collect, and fuse loop before you spend duplicate pets or chase unsupported rate claims.
Check duplicates first
Count the pets you can safely spare, test the five-to-one assumption, then keep leftovers visible so you do not break a collection or badge goal by accident.
Open the dedicated planner
For the dedicated tool view, open the Fusion Planner and compare the result with the fusion guide.

Recommendation
Claim listed codes first, then spend rewards only after you know which upgrade path stays useful.
Use exact game rates when they are available. Until then, treat this as a conservative planning helper.
Duplicate upgrade calculator
Enter a source rarity and duplicate count to estimate five-to-one fusion output. The inputs stay editable so you can test a target rarity without assuming an undocumented bonus.
Evidence boundary
What this calculator does not claim
Roblox confirms the game identity, creator, max players, and high-level mechanics; it does not expose current fusion costs, secret odds, or zone gates through the public description. Treat any exact value as a field to verify in game before publishing or spending around it.
