MARIMO: Cozy Moss Pet

Slow down with a tiny, round marimo by your side.

MARIMO is a cozy care game where you tilt your iPhone to roll your marimo around its aquarium, then look after its light, water, and cleanliness. Check in for a quiet moment during a busy day and build a gentle routine with your own living green companion.

■ A marimo that moves in your hands
Tilt your iPhone gently and watch your marimo roll across the aquarium. Enjoy the small, playful reactions as it responds to every movement.

■ A simple daily care routine
Give your marimo the light it needs, refresh the water, and keep the aquarium clean. Its color and expression change when care is overdue, and thoughtful care helps it return to a healthy state.

■ Feelings shown through expressions
Your marimo's face and messages change with its health and care conditions. Get to know a little friend that shares its mood without saying a word.

■ A practical marimo care guide
Open the Care Guide from Settings to learn helpful basics for looking after a real marimo, including light, water, and cleaning.

■ Save your favorite moments
Capture photos of your marimo and keep a record of the moments that make you smile.

MARIMO is made for slow, lasting care rather than fast competition or complicated controls. Begin a small, calming ritual with your green companion today.
