StreetPass virtual pet · Nintendo 3DS
Raise a pet that grows with every passing.
PetPal is a homebrew virtual‑pet game built around StreetPass. Every player you cross paths with — on the street or across the world — becomes a friend who feeds your pet, drops gifts, and nudges it toward its next evolution.
Runs on every 3DS & 2DS model

The idea
One pet. A whole world of friends.
You raise a single companion. It can't grow on its own — it grows by meeting people. Pass someone in town and StreetPass quietly trades pets in the background. Want to reach further? NetPass carries those encounters worldwide, so a friend in another country can show up in your journal tomorrow morning.

watched the trains. I think I'm
almost ready to evolve…

What's inside
A complete little game, not a tech demo
Everything below is already built — pets render procedurally, so it's fully playable before a single sprite is drawn.
✨
5-stage evolution
Hit encounter milestones at 50, 200, 500 and 1000 friends to push your pet through every stage.
🗺️
Real-time adventures
Send your pet on short, medium or long trips with per-location loot and a story that writes itself.
📡
StreetPass & NetPass
CRC-checked encounters, friend dedupe, gifts and friendship levels — locally or worldwide.
📖
An auto-written journal
Your pet keeps a charming diary of who it met and what happened, with achievements and currency to match.
💾
Saves you can trust
Versioned, CRC-validated, atomic writes with rotating backups and portable exports. No lost pets.
How it works
Three steps, then it runs itself
You pass someone
Close your 3DS and carry it. StreetPass trades pets with anyone nearby — NetPass does the same across the internet.
They become a friend
Each encounter lands in your journal as a friend, often with a gift and a bit of XP for your pet.
Your pet grows
Friends unlock new places, raise friendship, and tick you toward the next evolution. Open it up and watch.
