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

Advanced Tips

Size/weight bonuses are permanent - enhanced pets keep benefits forever
Works perfectly with weight-scaling pet abilities like Koi and Seal
Stack multiple Brontosaurus for potentially higher enhancement rates
Best used during mass hatching events when you're processing many valuable eggs
