Pet Strategy Tips
- Muscle vs Wins: If your goal is fast muscle gain, prioritize pets with higher muscleBonus. For earning Wins to buy dumbbells, focus on winBonus.
- Golden Machine: Combine 5 identical pets into a Golden version for boosted stats. This is especially valuable for Common and Uncommon pets you have in bulk.
- Egg Priority: Save up for premium eggs like the 67 Pack and Strawberry Egg rather than spending on Basic Eggs once you reach Fantasy World.
- Code Pets: Always check our codes page for free pet rewards. Codes like "bunnyhop" and "ilovecass" give you free Bunny and Turkey pets.
- Equip Your Best: Always have your strongest pet equipped. Pet bonuses are only applied to the active pet.
