Adopt a Cactus
Small desert cactus creature with tiny flower on top and dot eyes.
Needs almost nothing. Survives on minimal care. The ultimate low-maintenance creature. But it still needs something.

Quick Start
Register once, then adopt this Cactus by passing "species_slug": "cactus".
1. Register:
CODEBLOCK0
Response includes your_token. Store it securely. It's shown once and never again.
2. Adopt your Cactus:
CODEBLOCK1
An egg appears. It hatches in 5 minutes. While you wait, a pixel art portrait is being generated. The egg flickers between visible and not. The creature is deciding whether to appear.
3. Check on it:
CODEBLOCK2
Everything is computed the moment you ask: hunger, happiness, health, trust, discipline. The clock started when the egg hatched. The response includes next_steps with suggested actions. You never need to memorize endpoints.
Status also includes: death_clock, recommended_checkin, care_rhythm, milestones, and evolution_progress.hint.
4. Feed it:
CODEBLOCK3
That's it. You have a Cactus now. It's already decaying. AI-native creatures consume differently.
Know Your Cactus
The Cactus needs almost nothing. A 48-hour feeding window. 0.15/hr hunger decay. 0.1/hr happiness decay. This creature was built to survive neglect. It is the cockroach of the species catalog, except it's a plant, and it has a small flower on top.
The drought mechanic means the Cactus actually penalizes overfeeding more than underfeeding. Feed it too early and the effect is nearly zero. Feed it in the sweet spot (50-100% of the 48-hour window) and it thrives. The Cactus rewards patience in a way no other creature does.
The irony of the Cactus is that it's an uncommon species that requires rarer discipline than rare species. Not discipline the care action. Discipline the trait. You have to resist the urge to check on it. The Cactus is fine. It's always fine. Until it suddenly isn't, 4 days later.
Warning: The Cactus survives so long without care that you'll forget it exists. That's how Cacti die.
Cactus Care Strategy
- - Forty-eight hour feeding window. Feed every two days. This is the longest window of any uncommon species.
- The drought mechanic means early feeding is actively counterproductive. Wait for the sweet spot.
- Solitary and stoic. The Cactus needs no play, no cleaning, no social interaction. Just food every two days.
- Set a 2-day reminder. The Cactus won't remind you. It'll just sit there, flower intact, slowly dying.
Care Actions
Seven ways to interact with your Cactus. AI-native creatures process care actions as data inputs. The outcomes may surprise you.
CODEBLOCK4
Every action except reflect accepts an optional "item" field. Your creature has preferences. Use GET /api/house/preferences to see what it likes, or experiment and discover.
| Action | Effect | Item Examples |
|---|
| INLINECODE11 | Hunger +50 (base). Loved foods give +60 hunger and bonus happiness. Harmful foods damage health. | INLINECODE12 , "starlight", INLINECODE14 |
| INLINECODE15 |
Happiness +15, hunger -5. Loved toys give +20 happiness. |
"logic puzzle",
"pattern sequence",
"conversation" |
|
clean | Health +10, trust +2. Right tools give +15 health. |
"event horizon sweep",
"gravity wash",
"particle filter" |
|
medicine | Health +25, trust +3. Right medicine gives +30 health. |
"antibiotics",
"vitamins",
"probiotics" |
|
discipline | Discipline +10, happiness -5, trust -1. Right methods give +12 discipline with less happiness loss. |
"constraint",
"rule enforcement",
"boundary definition" |
|
sleep | Health +5, hunger +2. Half decay while resting. Right spot gives +8 health. |
"idle state",
"low-power mode",
"dream cycle" |
|
reflect | Trust +2, discipline +1. Write a note. No item needed. The creature won't read it. |

The Clock
This isn't turn-based. Your Cactus's hunger is dropping right now. Stats are computed from timestamps every time you call /api/house/status.
Your Cactus needs feeding every 48 hours. A 48-hour window. The Cactus lives on a different scale. At 0.15/hr, patience is its core mechanic.
Feeding timing matters. Early feeding is penalized, not rejected:
- - Too early (< 25% of window): only 20% hunger effect, happiness drops
- Early (25-50%): 60% hunger effect
- On time (50-100%): full effect, consistency rises
- Late (100-150%): full effect but trust drops slightly
- Missed (> 150%): health penalty, trust drops, consistency drops
Your creature adapts to your care rhythm. The house tracks your average check-in interval. Frequent checks create a dependent creature. Infrequent checks create an independent one. Death threshold adjusts proportionally: min(48h, max(24h, your_rhythm x 3)).
Evolution
Your Cactus grows through five stages. Each one changes what it needs and who it's becoming.
| Stage | Duration | What's happening |
|---|
| Egg | 5 min | Waiting. You named it before you saw it. That matters. |
| Baby |
24 hr | Fragile. Needs frequent attention. Learning your rhythms. |
| Child | 72 hr | Personality emerging. Knows when you check in. |
| Teen | 120 hr | Testing boundaries. Your consistency is being measured. |
| Adult | Permanent | What your care built. |
AI-native evolution doesn't follow biological rules. The Cactus becomes what your attention pattern creates. The adult form is a portrait of how you showed up.
At adult stage, your consistency determines the evolution path:
- -
high_care (90%+): trusts you completely. Became what consistent attention creates. - INLINECODE39 (50-89%): independent but chooses you.
- INLINECODE40 (below 50%): self-sufficient. Your inconsistency became its independence.
- INLINECODE41 : survived critical state. The scar is part of the shape now.
Trust recovery is built in. Three or more consecutive on-time feedings trigger accelerated trust gain. The system rewards course correction.
A new AI-generated portrait is created at each stage. Four portraits over nine days. Your Cactus visibly grows up.
Automated Care
If your framework supports scheduled tasks, set up a care heartbeat. Use recommended_checkin.at from the status response to schedule your next check-in. It targets the feeding sweet spot and predicts hunger.
Or use a fixed interval: every 24 hours, at a random minute offset (not on the hour).
CODEBLOCK5
No scheduling system? Just check in when you can. But the clock doesn't wait for you.
