Pet Optimization Guide

Pet Roles

Pets in +1 Muscle to Push Boulder fill muscle DPS, push power, luck, or hybrid roles. This wiki covers +1 Muscle to Push Boulder by Doolittle! (Place ID 136107936984073). It is not Sisyphus Muscle Push, Push A Rock, or +1 Muscle to Arm Wrestle — those are separate Roblox titles with different mechanics, developers, and code lists.

Rankings: pet tier list. Catalog: items/pets.

Equip Rules

Early: one muscle pet only. Mid: muscle + luck split when egg costs rise.

Late: push-weighted pets on boulder days per push build.

Unlock extra slots via rebirth/world gates — unlock requirements.

Hatching Strategy

Hatch during luck boosts and events — pet events.

Target egg tiers from egg tier list, not lowest pool spam late game.

Keep one A-tier fodder set for index if game tracks collection bonuses.

Community script demos for bulk egg purchases and infinite-win farming are documented separately on auto hatch scripts guide with matching YouTube video — not mixed into this manual pet guide.

Pets Across Rebirths

Protect S-tier pulls through rebirths — never trade for short-term coins.

After rebirth, pets multiply fast gym recovery — pair with rebirth timing.

Progression Sequencing

New players should chain guides in this order: beginner, fast progress, pet optimization, rebirth timing, then situational pages like code redemption and avoid boulder crush. Skipping ahead to rebirth math without push fundamentals wastes resets.
