🔎 Tamagotchi Gen 2 Evolution Finder & Character Calculator
Like Gen 1, the Gen 2 re-release is fully deterministic: child-stage care sets your teen, then care mistakes and discipline mistakes set your adult. Pick your path to see who you are raising.
A care mistake = you ignored a hunger or unhappy call. (Not cleaning poop does not count.)
A discipline mistake = you fed or played when it called for attention but did not actually want food or play.
Six adults plus the hidden Zatchi. One real day = one year of life.
The Growth Chart: Egg to Adult
Gen 2 follows the same five-stage life cycle as Gen 1, with its own characters at each step. One "year" equals one real day.
| Stage | Character | When |
|---|---|---|
| Egg | — | Hatches about 5 minutes after you set the clock |
| Baby | Shirobabytchi | First hour — a no-stakes "practice" stage; always becomes Tonmarutchi |
| Child | Tonmarutchi | From ~1 hour old until age 3 |
| Teen | Tongaritchi (good care) or Hashitamatchi (poor care) | Age 3 to 6 |
| Adult | One of six (see below) | Age 6 onward |
| Secret | Zatchi (English release) | Special unlock — see below |
As with Gen 1, the teen you become decides your ceiling: good care makes Tongaritchi (the path to the best adults), while sloppy care makes Hashitamatchi (steered toward the lower tiers).
Every Gen 2 Adult and How to Get It
Just like Gen 1, your adult is decided by your care mistakes (missed hunger/happy calls) and discipline mistakes (ignored attention calls). The headline character is Mimitchi — she went on to become one of the franchise's three permanent mascots alongside Mametchi and Kuchipatchi.
| Adult | Reputation | How to get it (from the good-care teen, Tongaritchi) |
|---|---|---|
| Mimitchi | The best — the iconic rabbit-eared mascot | 0–2 care mistakes, 0 discipline mistakes |
| Pochitchi | Good — the friendly dog | 0–2 care mistakes, 1 discipline mistake |
| Zuccitchi | The quirky one | 0–2 care mistakes, 2+ discipline mistakes |
| Hashizoutchi | Mid-tier | 3+ care mistakes, 0–1 discipline mistakes |
| Kusatchi | The plant-like neglect character | 3+ care mistakes, 2–3 discipline mistakes |
| Takotchi | Worst care — the octopus | 3+ care mistakes, 4+ discipline mistakes |
A poor-care teen (Hashitamatchi) leads toward Hashizoutchi, Kusatchi, or Takotchi.
The secret character — Zatchi: raise your Tamagotchi to Zuccitchi while never disciplining it (keep discipline at 0%), then give Zuccitchi near-perfect care (0 discipline mistakes) to unlock the hidden alien character.
Note for collectors: Japanese Gen 2 units use slightly different rosters — the Japan-only characters Nyatchi (a cat), Sekitoritchi, and Charitchi don't appear on the English/reissue version sold in Western stores.
Gen 2 Evolution Times: When Does It Evolve?
One real day is one Tamagotchi year, measured by the clock you set. Timings on the re-release:
| Evolution | When it happens | What decides it |
|---|---|---|
| Egg → Shirobabytchi | About 5 minutes after you set the clock | Nothing — automatic |
| Shirobabytchi → Tonmarutchi | About 1 hour after hatching | Nothing — always Tonmarutchi |
| Tonmarutchi → Tongaritchi or Hashitamatchi | Age 3 (day 3) | Care mistakes during the child stage: 0–1 = Tongaritchi, more = Hashitamatchi |
| Teen → Adult | Age 6 (day 6) | Care mistakes + discipline mistakes during the teen stage (table above) |
| Zuccitchi → Zatchi | With sustained good adult care — not automatic | See the Zatchi guide |
Evolutions happen while the pet is awake; a pet that evolves at an odd hour almost always has a wrong clock. See Gen 2 troubleshooting.
Weight and Age
Press A to cycle to the Age & Weight screen. Meals (hamburger) add 1 weight, snacks (cake) add 2, winning Higher or Lower removes 1. Heavy pets get sick and sickness costs care mistakes, so raise happiness with the game, not cake.
