2. Fold and crimp the sides toward the center.

3. Unfold and fold inward.

4. Fold into a triangle.

5. Fold the lower two corners diagonally upward.

6. Turn it around. Fold the two corners of the other side inward.

7. Then fold outward once to make the frog's legs.

8. Fold the top two small corners down and fold the top center corner down.

9. The paper frog is folded.

Frog sketch:

1. First, we draw two eyes on the white paper, and then draw a triangle for the body of the frog.

2. Then we draw a curved line under the triangle, and then we draw the frog's legs with a diagonal line first, and then we draw the feet with three short lines after that.

3. Draw the other two hands, and finally add a pattern to the frog's back and color it with watercolor pencils.

The frog (Latin name: Rana nigromaculata, alias: toad), the frog family side fold frog genus animals [1], the national third-class protected animals. It often inhabits rivers, ponds and rice paddies, etc., mainly in the grass at the water's edge, and sometimes can also lurk into the water. The frog has a flat head with a slightly pointed muzzle; the mouth is wide and consists of the upper and lower jaws; the eyes are large and prominent, born on the left and right sides of the head. The trunk is short and wide, and there is a small hole for the cloacal aperture between the two legs at the back end of the trunk, favoring the dorsal side. The forelimbs are short, consisting of five parts: upper arm, forearm, wrist, palm and finger, while the hind limbs are long and developed with webbing between the toes. The eggs are laid in the water and hatch into tadpoles, which breathe through gills. Reproduction of frogs is characterized by dioecy, fertilization in water and oviparity.

Frogs commonly found in farmland include the black-spotted frog, the zephyr frog, the golden-line frog, and the flower-backed toad. The bullfrog introduced from Cuba can be regarded as a "giant" among frogs, with a body length of up to 20 centimeters. Its mooing sound is very similar to that of a cow, so it is called bullfrog. Tree frogs in our country about a dozen species, they are light and thin, finger end of the sucker, good climbing tall tree trunks or small bushes, body color and the surrounding environment. The world's smallest frogs are hogweed frogs (Microhyla nepenthicola), scientists are in the Malay Archipelago's Borneo Island rainforest in and around the hogweed bush found this frog. Adult males of this newly discovered frog are about the size of a pea. This size makes them difficult to spot. Very fortunately for scientists, however, this frog is very vocal and has a loud call.
