Eggs — Hatch Machines & Pools

How Eggs Work

Eggs consume soft currency for random pet rolls. Each machine sits in a world zone with muscle or rebirth gates in +1 Muscle to Push Boulder.

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.

Priority order: egg tier list.

Zone Placement

Starter eggs live near first gym. Advanced eggs require push milestones on boulder route.

Unlock matrix: unlock requirements.

Luck Mechanics

Luck pets, boosts, and codes shift rarity odds — stack during farming sessions per pet guide.

Event eggs on pet events may override standard pools temporarily.

Spend Efficiency

Bulk hatch when income supports it; single pulls waste luck windows.

Balance with gym spending — gyms page and fast progress.

Item Economy Deep Dive

Items interact in a closed loop: gyms produce muscle, muscle unlocks pushes and eggs, eggs produce pets, pets multiply gyms, rebirth multiplies everything. Boosts and codes (when live) temporarily bend that loop — see boosts and codes. Misidentifying the game as Sisyphus Muscle Push or Push A Rock leads to wrong item expectations entirely.

Robux purchases, if offered, should be evaluated against time saved using honest review notes on the review page. Free players can complete core collection by following tier lists and build guides without paid eggs.

Wiki Methodology & Verification

This items/eggs article was last verified on 2026-07-08 against live testing in +1 Muscle to Push Boulder on Place ID 136107936984073. We prioritize in-game confirmation over datamine leaks, copied code lists from unrelated muscle simulators, or unverified social reposts. When Doolittle! ships a balance patch, numbers in tier lists, unlock tables, and calculator defaults may shift until we re-test.

Cross-linking is intentional: muscle progression touches gyms, pets, eggs, rebirth, and boulder routes simultaneously. Use the guides hub, tier list hub, and tools hub together rather than reading a single page in isolation. If you notice outdated text after an update, compare the in-game UI first, then check the latest updates page for patch notes.

Extended Reference Notes

Reference pass 1 for "items › eggs" documents practical habits top +1 Muscle to Push Boulder players use after 2026-07-08. Keep a personal log of muscle per minute at your best gym, current rebirth multiplier, and latest push checkpoint cleared on the boulder route. When any of those three metrics stall for two sessions, switch guides: training stalls → fast progress and gym tiers; push stalls → push build and crush guide; hatch stalls → pet optimization and egg tiers.

Account security matters as much as strategy. Never run unverified loadstrings from the auto train page on mains you value. Never paste Roblox passwords into code sites promising +1 Muscle to Push Boulder rewards. Official promo codes, when they exist, are plain text in the Roblox description or Doolittle! socials — not executable scripts. This wiki covers +1 Muscle to Push Boulder by Doolittle!
