Tetsu, a small fire spirit, waiting in his forge in the Tetsu Training Pal home screen — Tap him. Hold him for a hug.

River Otter

A calm swimming game with a wild streak. Leap and flip clear of the water, outswim a hunting pike, raise a family, and dress for the occasion.

Five places lie on the river bed, and each one keeps a single thing found nowhere else. Rising bubbles are the only clue.
