Care mistakes are the single thing that decides which adult you get on the Uni. Here is exactly how they are counted and what each count gets you.
The Rule That Catches Everyone
Care mistakes are cumulative across the Child and Teen stages. Four mistakes as a Child plus none as a Teen is still four mistakes when your Teen evolves. You cannot clean up a rough start at the last moment — an unhealthy Teen cannot become a healthy Adult.
Sickness Rate by Stage
| Stage | Sickness chance after a care mistake |
|---|---|
| Baby | Always sick once, 10 minutes after hatching |
| Child | 40% |
| Teen | 35% |
| Adult | 30% |
The Child stage is the riskiest — a mistake there is more likely to make your Tamagotchi ill than at any later point.
Care Mistake Counts for Every Adult
| From Teen | 0 mistakes | 1–3 | 4+ |
|---|---|---|---|
| Kuriritchi (M) | Mametchi | Weeptchi | Simagurutchi |
| Labilatchi (F) | Neliatchi | Milktchi | Momotchi |
| From Teen | 0–1 mistakes | 2–5 | 6+ |
|---|---|---|---|
| Gunchitchi (M) | Kuchipatchi | Shykutchi | Bigsmile |
| Teftetchi (F) | Woopatchi | Memetchi | Picochutchi |
| Curltchi (M) | Kikitchi | Unimarutchi | Gozarutchi |
| Tustustchi (F) | Mimitchi | Unimarutchi | Sebiretchi |
The Second-Chance Shortcuts
This is the part most guides miss. You can reach the top-tier adult even after making mistakes, if you hit an activity requirement.
| Adult | Normal requirement | Second chance |
|---|---|---|
| Mametchi / Neliatchi | 0 mistakes | 1–3 mistakes + Tama Walk at least 3 times |
| Kuchipatchi / Woopatchi | 0–1 mistakes | 2–5 mistakes + order from Tama Delivery at least 10 times |
| Kikitchi / Mimitchi | 0–1 mistakes | 2–5 mistakes + perfect score in 20 Tama Arcade games |
Tama Farm trips do not count towards the Tama Walk requirement. Only actual Tama Walks.
How to Make a Care Mistake (If You Want One)
Some adults require mistakes. To make one deliberately: let the hunger or happiness meter reach zero, wait for the attention beep, and leave it.
The Four Special Adults
Four characters bypass the teen-lineage system entirely and can come from any teen.
| Character | Requirements |
|---|---|
| Hypertchi (M) | Generation must be a multiple of 5 · born from a Tamaverse marriage · 3+ Tama Travel trips |
| Bubbletchi (F) | Generation must be a multiple of 5 · born from a Tamaverse marriage · buy 3+ Tama Fashion outfits |
| Simasimatchi (M) | Born from a marriage between two Uni devices · make 1+ DIY accessory as Child or Teen |
| Yattatchi (F) | Born from a marriage between two Uni devices · make 1+ DIY accessory as Child or Teen |
The rainbow egg tell: if you have met the generation and Tamaverse-marriage conditions for Bubbletchi or Hypertchi, you will hatch a rainbow striped egg. That is the game telling you the potential is there.
