Что под землей?

There is so much interesting stuff hidden underground! Don't believe it? Then quickly open the windows! The funny and curious hero of the book, a mole, will show you what root vegetables grow in the garden, what is inside a big anthill, and which forest animals' burrows are hidden under the roots of trees. You will also learn why an excavator digs a hole, what archaeologists find underground, and why subway trains go into tunnels beneath the city's streets.
For children up to 3 years old.
