Cerrellan - this rocky world is generally considered the "ugliest rock in space" by anyone approaching it from space. Grey and rocky, it has a cold and barren surface, with very few arable areas. However, underground, it is rich a vibrant, with vast underground mushroom farms, bug farms, and mineral deposits that are rich for mining. They are also famous for their breathtaking underground geode clusters, some of which can be big enough to fit Manhattan. The also have a unique geode that can form long, perfectly circular tubes that can stretch for miles, and can range in width from the size of a baseball to a half-mile in diameter. They can range in color to a pale-clear icy coloration, to red, blue, purple, green, and grey. The lighter to color, the rarer and more expensive the tubular crystal formation.
Praxonis - This world had a tragic flaw in its terraforming design - namely, the whole worlds was toxic. Plant life flourished, but a substance toxic to mammals spread in all the plants, the ground, and any potable water. The world was almost abandoned until an entomologist discovered over a hundred different varieties of insects on the planet that could eat the food without difficulty and neutralized the toxins in the water, the soil, and the plant life. These insects could be consumed safely, and not only were a good source of protein, but also tended to preserve the viitamins and minerals of the foods they ate in their bodies, as well. The colonists even discovered that if certain bugs ate certain plants, even certain tastes were preserved in the bugs, as well. This is why Cotton can claim to have eaten a cockroach-like insect that tastes like oranges.
