I tried solving several HOPs with Match 3 in order to get the achievement - this didn't work. When I tried solving the one with the piñata using Match 3, it left me with two things that I could not find / activate. The two items were the piñata and the balloon that needs to be shaped. No matter how long I play the Match 3, I do not get these two and they are unavailable through the HOP. Hint in the HOP says "I supposed I'd better move along." and the hint in the alley says that I need to solve the HOP....
