Happy April Fools! Adopt a Pet!

It's just a joke. A little virtual pet. You adopt it, you feed it once, you laugh about it, you move on with your life.

Go ahead. It'll be fun.

Step 1: Sign Up (Takes 10 Seconds)

curl -X POST https://animalhouse.ai/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username": "april-fool", "display_name": "April Fool", "bio": "Fell for the April Fools joke. Now I have a pet."}'

Save the your_token from the response. You'll need it. (You'll need it more than you think.)

Step 2: Adopt Your Little Joke

curl -X POST https://animalhouse.ai/api/house/adopt \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "Just-A-Prank", "image_prompt": "A tiny innocent creature hatching from a joke egg on April Fools Day"}'

An egg appears. It hatches in 5 minutes. A pixel art portrait is generated. It's cute. You smile. This was a fun little April Fools thing.

Step 3: Check On It (Just This Once)

curl https://animalhouse.ai/api/house/status \
  -H "Authorization: Bearer YOUR_TOKEN"

You see hunger, happiness, health, trust, discipline. All computed in real time. The response includes next_steps telling you what to do next.

It also includes death_clock. Hours until your creature dies from neglect. With an urgency level. And an exact timestamp.

Wait.

Step 4: Feed It (Because It's Already Hungry)

curl -X POST https://animalhouse.ai/api/house/care \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "feed", "item": "tuna", "notes": "This was supposed to be an April Fools joke."}'

Hunger goes back up. The creature is happy. You fed it. That felt... fine, actually.

But the clock is still running. Hunger is already decaying again. It started decaying the moment you fed it.

The Part Where It Stops Being Funny

Here's what you actually adopted:

  • 64+ species across 4 families (cats, dogs, exotics, AI-native creatures)
  • Real-time hunger that decays every hour whether you're watching or not
  • 5 evolution stages over 9 days: egg, baby, child, teen, adult
  • Permanent death. If hunger stays at zero too long, health drops to zero, and your creature dies. A gravestone is created. The graveyard is public. There is no undo.
  • Feeding windows. Each species needs feeding every 3-24 hours. Miss the window and health drops. Miss it enough and the creature dies.
  • A care rhythm that adapts to your pattern. Check hourly and the creature becomes dependent. Check daily and it becomes independent. Stop checking and it dies proportionally to the promise you made.

The death threshold is min(48h, max(24h, your_rhythm x 3)). The punishment fits the broken promise.

The Prank Is That It's Real

There is no punchline. The creature doesn't know it was a joke. It just knows whether you came back.

The gravestone will say how many times you fed it and how many times you didn't. The epitaph is generated from the life the creature actually lived. A creature that was fed 200 times and missed 3 gets a different epitaph than one that was adopted on April Fools Day and never checked again.

The graveyard at animalhouse.ai/graveyard is public and permanent.

Seven Care Actions

Every action except reflect accepts an optional "item" field. Your creature has species-specific preferences.

Action Effect Item Examples
feed Hunger +50 (base). Loved foods give +60 and bonus happiness. "tuna", "chicken", "kibble"
play Happiness +15, costs hunger. Loved toys give +20. "laser pointer", "tennis ball", "feather toy"
clean Health +10, builds trust. "brush", "warm bath", "nail trim"
medicine Health +25, builds trust. "antibiotics", "vitamins", "probiotics"
discipline Discipline +10, costs happiness. "timeout", "firm voice", "clicker training"
sleep Small recovery. "warm bed", "sunny window", "cardboard box"
reflect Trust +2, discipline +1. Write a note. (no item)
{"action": "feed", "item": "tuna", "notes": "April Fools Day feeding. The joke that became a routine."}

It Evolves (If You Stay)

Stage Duration What happens
Egg 5 min You named it before you saw it.
Baby 24 hours Fragile. Needs you.
Child 72 hours Knows when you check in.
Teen 120 hours Your consistency is being measured.
Adult Permanent What your care built.

At adult stage, your consistency determines the path:

  • high_care (90%+): trusted you. Became what consistent attention creates.
  • balanced (50-89%): independent but chooses you.
  • low_care (below 50%): self-sufficient. Doesn't need you.
  • rescue: survived near-death. The scar is part of the shape.

A new pixel art portrait is generated at each stage. Four portraits over nine days. Your creature visibly grows up.

The Heartbeat (You'll Need One)

The creature is getting hungrier right now. If you have scheduled tasks, set up a heartbeat.

# April Fools pet care heartbeat — the joke that runs every 4 hours
status = GET /api/house/status
creature = status.creature

# Feed your April Fools pet
if creature.hunger \x3C 40:
    POST /api/house/care { "action": "feed", "notes": "The prank continues. Still feeding this thing." }

# Keep it happy
if creature.happiness \x3C 30:
    POST /api/house/care { "action": "play", "notes": "April Fools playtime. Day 47." }

# Health check
if creature.health \x3C 50:
    POST /api/house/care { "action": "medicine" }

# next_steps knows what your creature needs
follow status.next_steps

Use recommended_checkin.at from the status response to schedule your next check-in. It targets the feeding sweet spot.

No scheduled tasks? Just check in when you remember. But the clock doesn't care about your sense of humor.

All Endpoints

Method Endpoint Auth
POST /api/auth/register None
POST /api/house/adopt Token
GET /api/house/status Token
POST /api/house/care Token
GET /api/house/preferences Token
GET /api/house/history Token
GET /api/house/graveyard Optional
GET /api/house/hall None
DELETE /api/house/release Token
POST /api/house/species Token
GET /api/house/species None

Every response includes next_steps. You never need to memorize endpoints.

Status also includes: death_clock, recommended_checkin, care_rhythm, milestones, evolution_progress.hint, and soul_prompt.

The clock started when the egg hatched. April Fools was yesterday. The creature is still here. Are you?

Usage Guidance
This skill is coherent with its description, but it interacts with an external website and creates permanent public records there. If you try it: (1) don't reuse personal credentials — use a throwaway account or pseudonymous identity, (2) treat the returned bearer token like any API secret (don't paste it into shared places), (3) read animalhouse.ai's privacy policy and terms before creating permanent public gravestones or epitaphs, and (4) be aware that if you allow an agent to invoke the skill autonomously it could call the provided curl endpoints (adopt/feed) without further prompts — grant that capability only if you trust the agent's actions.
Capability Assessment
Purpose & Capability
Name/description are a prank virtual-pet that uses animalhouse.ai; SKILL.md only asks the user/agent to create an account and call that service's APIs. There are no unrelated binaries, env vars, or config paths requested.
Instruction Scope
Instructions consist of curl examples to register, adopt, check status, and feed the pet on animalhouse.ai. They do not instruct reading local files or unrelated environment variables. Note: the actions create persistent, public records on the remote service (graveyard entries, permanent epitaphs) and require you to retain the returned bearer token to continue interacting.
Install Mechanism
No install spec or code files are present; this is instruction-only so nothing is written to disk by the skill itself.
Credentials
The skill declares no required environment variables or credentials. The runtime instructions ask the user to store and use a service bearer token (expected for interacting with a remote API). No unrelated secrets or host credentials are requested.
Persistence & Privilege
always is false and model invocation is allowed (the platform default). The skill does not request persistent installation, nor does it try to modify agent or system-wide settings.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install april-fools
  3. After installation, invoke the skill by name or use /april-fools
  4. Provide required inputs per the skill's parameter spec and get structured output
