The Iguanodon plays a very important role in the Gacha pod(s). They help you provide seeds for the Gachas.
You will want to set up your Iguanodon close to some fridges within your Gacha Farm area (A “Farm” can be any number of PODS.
You will bring in berries from your Automated Greenhouse, or from taking a tame out and harvesting berries.
Fill one or two fridges with berries as soon as you can. These allow real quick start of production. You can just take the berries and fill the Iguanodon to make seeds.
When you are ready to produce seeds, Fill the Iguanodon with berries, and go to the wheel and select Convert to seeds. The Iguanodon will convert some of the berries into seeds. Now you will need to transfer a minimum of 100 berries one way or the other to reset the convert to seeds option. I just transfer all to my inventory and back, then convert again, Once the Iguanodon Black Boxes, Transfer ONLY seeds to your inventory. If you play with it, you can max your inventory with seeds. Take those seeds and feed your Gachas. Come back and do it again for the next Gacha…
Once your Gachas are full, They will start making their crystals. You should fill several fridges with seeds. This will allow you quick access to seeds to fill the Gachas as soon as you log in.
I have found that it takes 3 – 4 fridges of seeds to fill each of my Cachas. I have a farm with 14 Pods. That is 28 Gachas . That works out to 112 fridges.
