Ola really enjoyed playing in the playground under the big, humming maple tree. One day she took her best friend, Stas, there. Together they swung, went down the slide and collected acorns, until finally they sat down on a bench under a tree to rest. Staś suddenly made big eyes. - Ola! Does your bench always smell like that? Ola sniffed the bench. It smelled of vanilla! And when she closed her eyes and sat down again, the bench smelled of chocolate! The children were very surprised. Staś tried to touch the bench with his tongue and felt that it was as sweet as candy. - Maybe it's a magic bench? - whispered Ola. Staś looked carefully around, and then they heard a quiet giggle from behind the back of the bench. This was the beginning of a whole new and unusual adventure....
