Striped(Полосатый)

One hot summer day, Nikolai went to the store to buy a watermelon. Tapping one after another, it seemed to him that one of them knocked in response. After bringing it home and swinging a knife, Kolya heard a knock again — the watermelon was communicating with him using Morse code. He introduced himself to 7293, and so their friendship with Nikolai began.
