Maybe not the best thing for battles but they are fantastic animals and I want a big one as a friend.
If this is a battle wagon I want the cockatrice back or a cassowary as they are very very angry birds.

Chickens are ruthless when allowed to be so a big one would probably pose a problem.
The cockatrice wears special glasses so it can't harm us maybe?
Or swap out with an big kiwi?

As long as I receive no ill effects from the cockatrice I'm picking the wagon.
More storage and I can bring friends thay way.

Depends on the chaos marine.
Some are gross and some are muscle people.
