The clodhoppers are hungry and the only food you have for them are a few bubble spore and a lot of bubble spore seeds. Bubble spore seeds are carried by the wind. Bubble spore plants make bubble spore seeds. Get the clodhopper population up to 100 by turn 300. Bubble spore plants create bubble spore seeds.
Clodhoppers eat both seeds and plants.
You have many seeds and few plants onboard your ship. Think about how you can maximize your seeds. In each mission, the wind currents are different. Slow the game to check the wind direction. Some bubble spore seeds can float on the wind for long distances.
