This origami frog is quite simple yet looks difficult to explain.
First, get a square paper and fold all corners to the middle.
Turn it over and fold all corners to the middle again.
Turn it over again and fold all corners to the middle one last time.
Turn it over and you'll get this.
Pinch two of those out to form the eyes.
Like this.
See the eyes? Then press down the mouth.
Flatten the feet.
