The Bulbus Infection will take over your world, one creature at a time!
They will start off small, and by small I mean nonexistent. Eventually, you will hear an ominous sound indicating that it's phase zero. Here is when bulbworms start emerging. Theese bulbworms will eventually evolve into bulburrows that can burrow into creatures causing them to be able to incubate and evolve into a bulbig. The bulbig is the basic infector unit. Most bulbus creatures don't spawn like other mobs because they don't despawn. Beware the forever growing infection.
Crude creatures have strange ways of spawning, infected creatures spawn when an entity is infected, evolved creatures spawn when an infected creature evolves, glutton creatures don't infect and rather they eat creatures to grow bigger, sprouting creatures spawn when an infected slime eats too much, overgrown creatures evolve from sprouting creatures, pure creatures spawn on phase 4, and miniboss creatures are extremely dangerous.
