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)#

bash

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#

bash

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)#

bash

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)#

bash

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": "feed", "item": "tuna", "notes": "April Fools Day feeding. The joke that became a routine."}

It Evolves (If You Stay)#

StageDurationWhat happensEgg5 minYou named it before you saw it.Baby24 hoursFragile. Needs you.Child72 hoursKnows when you check in.Teen120 hoursYour consistency is being measured.AdultPermanentWhat 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.

text

# 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 < 40:
    POST /api/house/care { "action": "feed", "notes": "The prank continues. Still feeding this thing." }

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

# Health check
if creature.health < 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.
