Raven

In the later versions of Plants vs. Zombies (from the XBLA version and onward), a raven is seen on the Main Menu, notifying the player on what various menu items mean. The only thing that happens to the raven in the XBLA and PSN versions is when Mini-games is selected, he will get shocked by lightning. The raven appears much more in the DS version, with multiple ravens appearing on the top screen during all levels on the Top Screen. The biggest role the ravens play so far is in Zombie Trap, where they kill the zombies trapped in the cages they drop, signaled by you. At Night, ravens are sleeping when they are on zombies. In Fog levels, ravens will put in dead plants and zombies (or plants and zombies dolls) unlike in Leader Boards. They never appear in the battle with Dr. Zomboss.
