More Longrass Tips

Use dinosaurs to attack bushes, then check their inventories. They'll have a bunch of seeds and sometimes have longrass seeds.

Just get your dino such as bronto stego parasaur (ect) and wack the bushes then you will get seeds ang plant them in a medium or large crop container (I'd recommend to keep it in there until you need it because it spoils very fast outside of it)

If u wanna get some of these I would say take your anky on an argue up there and harvest some bushes or the rare flowers too get some.
