Trivia

 * It attacks similarly to Cattail from first game. However, it only shoots one needle as opposed to Cattail's two. So, each spike now deals two damage instead of one.
 * This, Power Lily, Pea-nut and Ghost Pepper are currently the only premium plants that do not appear in Plants vs. Zombies.
 * This and Ghost Pepper are currently the only premium plants that cost gems instead of real money.
 * If it is fed Plant Food with no zombies on screen, the leaves it throws will not be blue.
 * It is based off of the Onopordum acanthium, a species of thistle and an ancient celtic symbol.
