Through the window, Dawid watches a new neighbour move into a house next door. The girl is more or less his age. She's wearing a strange skirt. Later on, Dawid finds out it's a Hawaiian hula skirt and the girl's name is Monika. Most probably, he also learns why Monika's grandma has gone away to Hawaii. Most probably, he's going to tell her that his sister is a cat now. For sure, the boy and the girl will be brought closer together by their strength in order to save their precious memories about the loved ones who departed this life. The mad Time Hopper will help them cross the gate in an old clock that leads to a place where time rules are completely different. Yet, in order to pay him, is chocolate enough?
