The structure of the book

The worksheets are divided into two parts:

In the FIRST PART (sheets 1-40) you need to collect all the equipment. When aunt Olga says a riddle, you need to stick the correct sticker on the camping page, wherever you want.
After you have got all 8 stickers (by choosing carefully because there are extras!), you are ready for the second part of the trip.

In the SECOND PART (sheets 41-80) other activity sheets are found. Here, aunt Olga will show you which pieces of the puzzle need to be inserted in the grid at the back of the book. When all 16 pieces are put together, the mystery of the ancient medallion (in the first book) or the mystery of the pretty dolphin (in the second book) will finally be solved!
