Creating a species

This page walks you through making a new species and explains the three kinds you can create. You don’t need any technical knowledge — just follow the prompts.

​

1. The three kinds of species

What kind of species you end up with is decided by how many member species you add to its recipe — you never set the “type” directly:

A recipe with a single member isn’t a valid species, so the wizard won’t let you finish until you’ve either added zero members (a truebred) or two or more (a hybrid). The FINISH button stays hidden until the recipe is valid.

Each hybrid must use a unique set of species. If a hybrid — true or composition — already exists with the exact same set of member species, the wizard won’t let you create another one. Only which species are in the mix matters; the percentages are ignored. The check runs the moment you press FINISH, and you’ll be told which existing species already uses that combination so you can adjust the members.

Every member in a hybrid recipe has a percentage (its share of the mix), and the shares always add up to 100%.

​

2. Starting the wizard

When you begin, you’re asked whether to Clone an existing species or start from Basic.

• Basic — build a brand-new species from scratch (covered below).
• Clone — copy an existing species as a starting point, give it a new name, and confirm. Handy when your new species is a small tweak of one that already exists. (See §7.)

Choosing Basic next asks: Purebred or Hybrid?

• Purebred → make a truebred (§3).
• Hybrid → open the composition builder to add member species (§4 and §5).

AI presets (right after you name the species). Once you’ve named a new species, the wizard asks the AI to prefill best-guess fertility values based on the name (and any descriptors), then shows them on a review menu — each value is its own button. Tap a value to change just that one (the wizard asks for the new number and drops you back on the menu), and press FINISH when you’re happy with them. The suggestions are always sanity-clamped to valid ranges, and if the AI is unavailable the menu simply starts from sensible defaults, so creation is never blocked.

​

3. Creating a truebred

A truebred is a species that stands on its own — it has no member species in its recipe.

1. Choose Basic → Purebred.
2. Name the species.
3. On the review menu, tap any species specifics value to adjust it, then press FINISH (see §2 and §6).
4. Optionally define descriptors (appearance tags) — you can describe the look in your own words and let the AI turn it into tags, or Skip.
5. Review the summary and confirm.
6. Name the founding Mother and Father — these two become the species’ original ancestors (its root lineage). See §6 “Founding pair”.
7. Confirm — the species and its founding pair are created together.

​

4. Creating a hybrid (two species)

A true hybrid blends exactly two species.

1. Choose Basic → Hybrid to open the composition builder.
2. ADD your first member species. The first member automatically holds the remainder of the mix, so you aren’t asked for a percentage yet.
3. ADD your second member species. Now you’re asked what percentage this species makes up — enter a whole number greater than 0 and less than the remaining amount. The first member’s share shrinks automatically so the total stays 100%.
   • Example: add Sergal first, then add Fennec at 70% → the recipe becomes Sergal 30% / Fennec 70% (Sergal takes the leftover 30%).
4. With two members in the recipe, the FINISH button appears. Press it. (If those two species already form an existing hybrid, the wizard sends you back to adjust the members — see the uniqueness rule in §1.)
5. Name the species, then review/adjust the AI-suggested fertility values on the menu and press FINISH (§2, §6); optionally add descriptors, and review.
6. Name the founding Mother and Father.

​

What’s special about a true hybrid’s founding pair

For a true hybrid, the founding pair’s lineage (genes) is bred from the two member species’ own lineages rather than starting fresh:

• Mother = member A’s mother × member B’s father
• Father = member A’s father × member B’s mother

You still type the Mother and Father names you want — only their ancestry is derived automatically, so a Sergal+Fennec hybrid is genuinely descended from both Sergals and Fennecs. The confirmation screen shows both the derived lineage and the names you chose.

If one of the two member species has no lineage of its own to breed from, the wizard will stop and tell you, rather than create an incomplete species.

​

5. Creating a composition hybrid (three or more species)

A composition hybrid blends three or more species. The steps are the same as a true hybrid, you just keep adding members.

1. Choose Basic → Hybrid.
2. ADD the first member (it holds the remainder — no percentage asked).
3. ADD each additional member and give it a percentage (greater than 0, less than what’s left). The first member keeps shrinking to hold the leftover so the total is always 100%.
   • Example: Sergal (first), then Fennec 50%, then Kobold 20% → Sergal 30% / Fennec 50% / Kobold 20%.
4. You can keep up to 9 members. Each member’s button shows its current percentage so you can see the mix at a glance. Selecting a member removes it (and its share returns to the first member).
5. Press FINISH (available once you have at least two members). If this exact set of species already exists as a hybrid, you’ll be sent back to adjust the members (see §1).
6. Name the species, then review/adjust the AI-suggested fertility values and press FINISH (§2, §6); optionally add descriptors, and review.
7. Name the founding Mother and Father — for a composition hybrid these are ordinary named root ancestors (a fresh lineage), just like a truebred.

​

6. The questions every species answers

Whichever type you make, the wizard collects the same core details. It enforces sensible minimums/maximums for each and will re-ask if a value is out of range. These are pre-filled with the AI’s suggested values right after naming (§2); on the review menu you can tap any one to change it, then press FINISH. Species specifics (reproductive profile):

1. Ovulation cycle — how many days between cycles (minimum 4 days).
2. Ovulation period — the fertile window within the cycle.
3. Ovulation count — how many ova can be released.
4. Gestation period — how long a pregnancy lasts.
5. Growth period — how long offspring take to mature (at least the ovulation cycle length).
6. Uterus size — adult uterus volume in millilitres (an average adult human is ~60 ml, for reference).
7. Embryo size — the maximum volume an embryo can reach (within a min/max the wizard derives from the uterus size and ovulation count).
8. Birth type — how offspring are born:
   • Live (live birth)
   • Ovum (egg-laying)

Descriptors (optional): appearance/behavior tags. Describe the species in your own words and the AI generates a tag list you can keep or skip. Founding pair (Mother & Father): every species is seeded with two original ancestors.

• Truebred & Composition hybrid: you name a Mother and a Father who become the species’ fresh root lineage.
• True hybrid: you still name them, but their ancestry is bred from the two member species (see §4).

The species and its founding pair are always saved together, so a species is never left without its lineage.

​

7. Cloning an existing species

If your new species is close to one that already exists:

1. Choose Clone at the start.
2. Search and pick the species to copy.
3. Give the clone a new name and confirm.

The clone copies the original’s recipe and specifics as a starting point. (Note: you can’t base a new hybrid on an existing composition hybrid as a member — composition hybrids aren’t offered in the member search — but you can clone one directly.)

​

8. Rules & tips at a glance

• The type follows the recipe: 0 members = truebred, 2 = hybrid, 3+ = composition hybrid. You never pick the type label directly.
• AI presets save time. Right after naming, accept the AI’s suggested fertility values to skip the questions entirely, or customize them — the suggestions are always clamped to valid ranges.
• Shares always total 100%. The first member you add holds the leftover, so you only type percentages for the additional members.
• Enter whole percentages (e.g. 70), greater than 0 and less than what’s left. The first member can’t drop to 0, so you can’t give a later member the entire remaining share.
• FINISH appears only when the recipe is valid — i.e. two or more members for a hybrid.
• Hybrids must be unique by their species set. You can’t FINISH a hybrid whose exact combination of member species already exists — percentages are ignored, only the set of species counts.
• Up to 9 members in a composition.
• Remove a member by selecting its button; its share returns to the first member.
• Names matter: always give real Mother and Father names — for a true hybrid these label a pair whose ancestry is bred from both member species.

In short: pick Purebred or Hybrid, (for a hybrid) add two or more member species with their percentages, answer the species’ reproductive details, optionally tag its appearance, and name its founding Mother and Father. The number of members you add decides whether you’ve made a truebred, a hybrid, or a composition hybrid.
