They appear randomly.
Although frogs may not appear to have hips, they do have modified hip bones. Their hips and spine aid in jumping.
Their eyes appear to be red sometimes.
because they like the extra moisture.
i suppose that ffrogs and toads appear after rain because they like the mud and the environmental change
Yale Drama School
A frogs eye can be many colours, normally they are brown blue or green
usually, the frog would come from the nearest pond/lake. If there is not a nearby pong or lake, frogs would live near damp grounds, and would go hunting for food in wet weather.

Most frogs and toads do not live in water, but are rather terrestrial (living on the forestfloor) or are arboreal (living in shrubs and trees). A lot of species from the Ranidae-family are more aquatic (eg leopard frog), and only some frogs are only to be foud in water, like the Surinam toad. But frogs like these are exceptions.
Frogs are not actually green. They appear green so they can blend into their environment for defence. Frogs have no green pigmentation in their skin at all. Like mammals, they are unable to produce green pigment. Mammals, reptiles and amphibians can only produce black and yellow-red pigment, and all colours and patterns on a frog's skin are the result of different combinations of these two pigments. Frogs contain variations of the yellow-red pigment. Most species of frogs appear green because of the pattern of refraction of blue light by special cells in their skin blending in with this yellow pigment.
Yes, frogs generally can be called carnivores.Specifically, frogs can be considered carnivorous since they generally favor an animal tissue-based diet. But they consider what is immediately available in the environment and plan their diets accordingly. It therefore is possible to find frogs that appear to be omnivorous in opportunistically feeding on animal and plant tissues and others that survive as plant-eaters.
