It hatches into a little blob that lives inside the console.
Play GEM CATCH with it, keep it clean, let it sleep. Care points feed the Hall of Fables like any other cart.
One visit a day earns a stamp and a streak bonus.
After three stamps it grows up — and which way it grows depends on how you raised it:
soft & round — the well-fed, well-rested path
quick & spiky — raised on play and motion
calm & wise — the patient, steady carer's pet
Send it off and hours later it comes home with a postcard, points, and a wearable souvenir — a race helmet, wizard hat, star badge, antenna, or wing sandals.
The INFO page prints a 7-character code (base-30, checksummed) packing its form, console badges, streak, stamps and current accessory:
The egg screen has a PET IMMIGRATION office that adopts a pet from any code. Sibling
consoles read/write the same fable-pet-v1 record — so one
pet really can tour the whole family.
No matter how long you're gone — a day, a month — it never decays past that cap.
Worst case is a fresh streak. Trips can be called home early with no penalty.
If total neglect ever turns it into a little ghost, bringing it back costs nothing — and it keeps everything.
