Daily in townsville there was a skyscraper filled with trash and people living in it. Aku would come once a day and just kind of observe them. Bubbles finds out and comes and fights him every day but she is no match for him. So she gets the idea to trail him. At first it is observation of what he does in the tower. Nothing he just walks and watches. Then she follows him from his origin point at the start of the day. A s he walks a dog on a tricycle approached him and shot him with a large mounted barista with a rope through the chest. Then the tricycle flies off into the air with Aku and the dog and Aku start chatting. Then I awake.
