Jam Hsiao was a boss in Plants vs. Zombies: All Stars during the Jam Hsiao event. He had four stages of health. His ability was to deal damage to two enemies. His boss skill was to play a grand piano that deals damage to all plants. He had three kinds of pianos and he could use one of them every four turns.
- Jam Hsiao is a real person, specifically, a musician.
- This makes him one of the few zombies to be inspired by real people, the other being Dancing Zombie pre-GOTY update.
- Coincidentally, both of them are inspired by musicians.
- The first part of his special skill slightly resembles Pianist Zombie playing his piano.
