User blog comment:Intrepid potato mine/Piñata Party-a useful and glitchy source of coins and costumes for Plants vs. Zombies 2/@comment-30553109-20180531215930/@comment-35403335-20180531235127

Just do the glitch on party 1 and you'll see. The game will somehow think you played the previous party(party 5), and you'll get tons of senor pinata. Not sure if it works the same on all devices though.
