Growing these are ez all you need is the iguanadon tap it for seeds (you have to put the narcoberry in the iguanadion) get feces and water from poles or rain then wait then you have narco Berrys ;)

For me at least, use an anky, it gets so much of these especially if you have a huge area of land with bushes. In my opinion and from my experience, much better then the brontosaurus
