Shamrockstar is a plant in the game Plants vs. Zombies Adventures and is the VIP version of Shamrock. The player obtains it after completing Mildew Meadow Level 7. Unlike Shamrock, this plant will hide if any zombie is on the tile right in front of it. This being with Shamrocks, they will hide if any zombie is in a 3x3 area of them. Even so, this plant packs a solid punch. When the situation calls for long distance firepower, this is the best plant to use. When this plant is used alongside Acespearagus, the player will have a very potent, long range zombie-killing combo that will last long.
