GYAO! — Virtual Pet Mini-Game Guide

A Tamagotchi-like mini-game accessible from Dave's phone. Raise a virtual pet from roe to full-grown fish, care for its needs, and discover all 14 evolution variants.

How to Unlock GYAO!

Complete the "Stormy Night" side quest from Sato. This late-game quest requires diving into a whirlpool to defeat the Mantis Shrimpboss. Upon victory, GYAO! is unlocked and appears as a new app on Dave's phone.

💡 Tip:You do not need all 14 species. The "GYAO! Master" achievement only requires raising 5 fully evolved GYAOs — any species counts.

Life Cycle

Each in-game day equals one GYAO year. The life cycle progresses through time slots:

RoeHatchlingFrySmall FishAdult
  • Roe — 1 time slot, cannot interact
  • Hatchling — 1 day
  • Fry — 1 day; affection determines orange vs blue path (3–4 hearts = orange/docile, 0–2 = blue/ferocious)
  • Small Fish — 2 days
  • Adult — final stage; food & love stats determine exact species

GYAO! Care Tabs

🍽️
Meals
Track GYAO's hunger level. Feed portions are displayed as you feed. Overfeed and GYAO refuses to eat.
🍬
Snacks
Give snacks to slightly increase affection without filling the food bar. Candy makes GYAO like you more.
🎮
Play
Play the shell game (find the pearl under one of three conch shells) to increase affection. +2 intimacy per success.
🧹
Clean
Press clean when excrement appears on the sides of the tank. Leaving poop for a full day leads to death.
💊
Heal
A purple skull icon appears when GYAO needs medicine. Press the medicine button to cure it immediately.
💡
Lighting
Turn off lights in the evening before running the restaurant so GYAO can sleep well.
⚠️
Warning
Lights up whenever GYAO has an issue (hunger, sickness, dirt, or needs discipline). Not a button — an alert.
📏
Discipline
When GYAO makes unusual sounds but has no apparent need, discipline it. +3 training blocks per use. Decreases if cues are missed at night.
⚙️
Options
Turn phone notifications on/off for GYAO. Gives you a break when you do not want to play.
📖
Memories
View and remember your previous GYAOs that have passed away.
📊
Manage
Visualize progress, age, and current weight of your GYAO.
🔄
Revive
After GYAO dies, revive to get a new egg and start the life cycle again. You do not need different species for the achievement.

Special Evolutions

Two GYAO can evolve again after reaching adulthood. These require maximum training bars at specific ages.

BelugaWhale Shark
Max training bar before age 9. If not met, Beluga dies at age 9.
Lemon SharkOrca
Max training bar at age 12. If not met, Lemon Shark dies at age 12.
⚠️ Important: Beluga must be fully trained before age 9, and Lemon Shark before age 12. Failure means they die when that age is reached.

Pro Tips

  • Best time to revive: In the afternoon. Your GYAO will age up between time slots, making the final evolution happen at night so you have the day to make adjustments.
  • Grinding the achievement: You do not need 5 different species — just raise 5 fully evolved GYAOs. Let each one die, then revive and repeat.
  • Save often: Keep a backlog of saves so you can reload if your GYAO evolves into the wrong species or loses training levels.
  • Speed up with time skip: Time skip mechanics work on GYAO progression. Use them to fast-forward through cycles.
  • Discipline at night: Turn off the lights first so the sleep notification does not mask the discipline cue.
  • Emergency stats adjust: Give an unnecessary injection to lower intimacy by 1 if you need a specific evolution. There is no way to manually lower food level.
  • Press ESC to skip the animation after performing any action — it registers the effect immediately.
🏆 Achievement:"GYAO! Master" — raise 5 fully evolved GYAOs. You also receive a unique boat skin on raising your first.
