- Value
90
Best For
- Pet breeding optimization - 5-20% size/weight increase for all hatched pets
- Long-term pet scaling - permanent boost capped at 30% per egg for sustained advantage
- High-value pet enhancement - maximizes stats for expensive pets like Kitsune, Blood Owl
- Ostrich synergy builds - combines size boost with age acceleration
Pro Strategies
Pre-Hatch Positioning Strategy
- Deploy Brontosaurus before starting major egg hatching sessions to ensure all pets receive the size/weight bonus. The 5-20% increase applies only to newly hatched pets, not existing ones. Position centrally where it can affect all your hatching locations.
High-Value Target Focus
- Use Brontosaurus when hatching expensive, rare eggs like Divine Egg, Culinarian Chest, or event eggs. The 30% size cap provides maximum benefit to pets that are hardest to replace and most valuable for trading or gameplay.
Ostrich Combo Method
- Combine with Ostrich for the ultimate pet enhancement setup. Brontosaurus provides size/weight boost while Ostrich gives age advancement. This creates newly hatched pets with both increased stats AND advanced age for immediate high-level performance.
Breeding Program Setup
- Establish breeding programs where you continuously hatch eggs under Brontosaurus influence. Each egg gets up to 30% bonus, creating a lineage of progressively stronger pets. Focus on pets with weight-scaling abilities for exponential benefit from size increases.
Alternatives
Common Mistakes
- Placing Brontosaurus after pets are already hatched (no retroactive effect)
- Wasting the 30% size bonus on cheap, common pets instead of valuable ones
- Not combining with Ostrich for maximum pet enhancement synergy
- Forgetting that Brontosaurus doesn't buff other Brontosaurus pets
