Clone to Steal Eggs Mutations Guide

Mutations and egg sizes are how Clone to Steal Eggs turns a normal hatch into a pen that funds rebirths. Two pets with the same base species can earn wildly different Cash per second once a Gold, Diamond, Radioactive, or Rainbow roll lands, and a Huge egg can outclass a Baby of a higher rarity name. This guide explains the mutation filter names used across scripts and hubs, how sizes fit the economy, and which keepers deserve slots versus auto-sell.

Exact percentage odds are not published in a reliable official table for this title, so we avoid fake hatch-rate charts. Instead we focus on practical decisions you can make every session with Manage Clones, Luck Potions, and the tier list.

Mutation types you will see

Community filters and farm tools consistently expose these mutation labels:

Mutation	Practical take
Normal	Baseline hatch. Fine for filling empty slots early.
Gold	First meaningful upgrade over Normal for most species.
Diamond	Strong mid upgrade — often worth replacing a Normal of the same pet.
Radioactive	High-value roll; keep unless a clear Rainbow or better species arrives.
Rainbow	Top cosmetic/economy roll in common filter lists — prioritise slots.

Treat the table as a priority ladder, not a promise that every Gold beats every Normal of a stronger species. A Magia Yeti Normal still wrecks most early Gold commons. Always compare Cash/s on the pet card after hatch.

Egg sizes: Baby, Big, Huge

Size rolls independently of mutation colour in the filters players use:

• Baby — smallest; usually weakest income for that species.
• Big — middle tier; solid upgrades over Baby.
• Huge — largest; often the difference between “nice hatch” and “rebirth fuel.”

When auto-sell is available in Manage Clones, many players sell Baby commons aggressively while keeping Big/Huge eggs for hatch. Pair size filters with rarity filters so you do not delete a Huge Secret because the species name looked unfamiliar — check pets if you are unsure.

How to hunt better rolls without inventing odds

1. Raise the zone only as far as your Speed allows (egg zones). Higher areas are where stronger eggs and mutation chatter concentrates.
2. Pop LUCK1 (or a shop Luck Potion) when you are about to hatch a batch from mid/high zones (potions).
3. Fill every active slot first. An empty slot earns zero — a Normal Baby still beats nothing.
4. Replace the weakest Cash/s pet whenever a new hatch wins on the card, mutation or not.
5. Protect Rainbow / Radioactive keepers during auto-sell setup so scripts or filters do not dump them (scripts).

Mutations vs species tier

Use both lenses:

• Species ranking: tier list and code pets like Magia Yeti.
• Mutation/size ranking: this page.

A Rainbow of a low species can still lose to a Normal of a late-game earner. Conversely, mutating your best species is how free-to-play accounts catch paid treadmill players. After Saturday patches, re-check whether new eggs reshuffled the tier list (updates).

Pen management habits that compound

• Hatch promptly — eggs sitting unopened do not earn.
• After each hatch, sort by Cash/s, not by how cool the model looks.
• Keep one “project” slot for a mutated mid pet you are building around, but do not hoard six project pets.
• When rebirth is affordable, take it — mutations stay; only the listed Cash cost is spent (rebirth).

Common mistakes

• Auto-selling every non-Rainbow before reading Cash/s.
• Ignoring Huge sizes because the mutation is Normal.
• Chasing mutations on Starter zones for an hour instead of training Speed.
• Leaving Magia Yeti unequipped while admiring a shiny but weak Gold common.

Where this guide sits in the loop

Redeem codes → train Speed and set zones → hatch with Luck windows → keep mutations/sizes that win → rebirth → repeat. For the day-one path see Getting Started. For AFK sessions that feed eggs while you are away from the keyboard, read AFK farm.

Mutations are not a separate mini-game. They are the multiplier layer on top of zones, clones, and treadmill discipline. Treat every hatch as a Cash/s audit and your pen will fund the next gate without Robux panic buys.
