Laugh and cry,
just as you feel.
A conversational AI app
that’s like a true friend.

This is Happy Island,
a dreamy paradise floating on the sea.
A place where animals light up the stage,
where joy shines on every face.

Chunta, a little mouse
who dreams of becoming
a Star Animal on stage someday,

joined by companions
who chat with spirit,
just like humans do.

Chunta, so easily shaken,
tears falling without warning—
a little soul who hates to be alone.

Little by little, as he chats with you,
his heart slowly starts to open.

A dependable senior,
a playful comedian—
these animals feel so alive,
as if they truly understand you.
And as you talk with them,
you slowly realize…
they've become
your friends.

And now…
Welcome to Happy Island.
