First, you draw a large oval in a 45-65 degree angle.
Second, you draw another oval at a 5 degree angle.
Third, you draw a foot, with webbed feet.
Then draw the arms. Have them only have 3 or 4 fingers.
Fifth, draw a circle on the upper part of the first oval. Add a pupil to finish the eye.
Then, erase the top of the first oval, draw a half oval in the erase part, then add a tongue to the edge of the bottom lip.
Then draw small circle with two tiny wings on each side of the circle on the tongue on step 6.
Finally, draw a random pattern on your frog.
That is how you draw a frog.
