There are many diseases on planet Eura. Bacteria and viruses cause them as well as other things, like the metamorphic air plankton. The zantraliss virus is a virus that is similar to the common cold, it is deadly to humans but not deadly to the native life of Eura. Bacteria causes zaralitus, it infects the bird like creatures of the jungle biome and sky whales. It causes minor bloating, itchiness and death. Metamorphic air plankton causes zala condition in Pingaloafs. When inhaled it starts rapidly replicating in the Pingaloaf’s lungs then it starts clumping into large clumps of air plankton which fuse into worms. Some stay in the lungs to become females others migrate to the kidneys to become males.
