腐化物
Rot is a type of creature consisting of numerous cysts with tentacles to draw prey in. It consumes almost all creatures, sometimes including other types of Rot, and can instantly kill Slugcat if they are drawn in. Most creatures are afraid of Rot and avoid it whenever possible.
Mobile Rot
黄长腿菌
黄长腿菌 are the smallest mobile Rot cysts and are primarily found in 垃圾堆. They are both blind and deaf, relying solely on their tentacles to feel and draw in prey. Because of their size, they are too small to consume large creatures like 绿蜥蜴 and 秃鹫, although these creatures are still afraid of it. Brother Long Legs are often colored brown to indicate their type, although some Brother Long Legs are colored blue like 蓝长腿菌.
蓝长腿菌
蓝长腿菌 are larger Rot cysts initially encountered in 外缘, and although blind, can detect creatures with their hearing. They are large enough to consume most creatures and even 黄长腿菌, and are a formidable opponent that is often futile to fight. Daddy Long Legs flash in color whenever they hear sounds, often rushing to the source.
Daddy Long Legs are often colored blue to indicate their type, although very occasionally, brown Daddy Long Legs can be encountered in regions like 垃圾堆.
紫长腿菌
贴壁腐化物
Proto Rot is an unkillable stationary hazard that can consume creatures that touch its cores or short tentacles. It is often colored brown or blue to reflect the mobile rot found nearby. Blue Proto Rot can flash to indicate that it hears noises, though this is solely a cosmetic effect, since it cannot move.
Proto Rot is often accompanied by static tentacles hanging around which Slugcat can safely grab onto and climb.
Origin
This section contains major plot details from the "5P" region and beyond. If you have not progressed past this region, then read no further!
Rot originated from 五块卵石 when he attempted to circumvent the self-destruction taboo[1] and failed. Initially, Rot was dumped into the 垃圾堆 while it was still in the form of 紫长腿菌, and this is the form it takes during 矛大师's campaign. Over time, it degraded into 蓝长腿菌 and then 黄长腿菌, which is the form it takes in most Slugcats' campaigns.
By 溪流's campaign, Five Pebbles has been unable to prevent the runaway formation of Rot and his superstructure is once again filled with 紫长腿菌, 蓝长腿菌, and lots of Proto Rot, even changing the name of the region to 腐化之地. By 圣徒's campaign, this has degraded into only a handful of 黄长腿菌 in 无声构造, after his superstructure collapsed.
