There are three extant species. The most common of these, the southern cassowary, is the third-tallest and second-heaviest living bird, smaller only than the ostrich and emu.
Cassowaries feed mainly on fruit, although all species are truly omnivorous and will take a range of other plant food, including shoots and grass seeds, in addition to fungi, invertebrates, and small vertebrates. Cassowaries are very shy, but when provoked they are capable of inflicting injuries, occasionally fatal, to dogs and people.
In Venture, The Cassowaries are basically lesser versions of the Emus. They are also immune to ranged attacks, and will explode just like the Emu.
Cassowaries were also involved in the Emu rebellion, and were known for torturing many Venturians. Just like Emus, they tore up the bodies, burned them, ripped up their guts and also cut them in half with their giant sickle claw.
