Let's imagine the forest and all its animals!
During the daytime, when the sun is shining, you can hear birds singing happily in the trees. There's a big moose eating grass; it’s very big and gentle. Also, little squirrels are busy running around, looking for cones to eat and store for later.
But when the night comes and it gets dark, the forest changes. Now, a lynx (which is a wild cat) quietly moves around looking for food. You can also hear the sound of frogs croaking near the water, making a fun nighttime song.
Isn't it amazing how the forest feels alive all day and night, just with different animals!
