How to distinguish Roflimo? (Voidtrain)
It seems that there should be different specializations and how to determine which one is in the cage? Is it possible to remove it from the perch without breaking the structure?edikbl
By color for example. About the second xs.
Spoiler 
I have met 3 species so far.
1) pink - brings organic matter and scrap metal (Fig. 2)
2) Black and white - HZ sits and does not bring nicherta (Fig. 3)
3) White-pink (with an "x" in place of the nipples) - HZ sits and nicherta does not bring (Fig. 1)
There is also a difference in pupils and eye color, no idea what it affects.

On one of the sites they write:
SpoilerDealer
He simply swallows everything that he meets in the entrance, and then spews it out into the so-called common fund of the colony.
Defender
Simply yells at those who are trying to harm his house. So much so that it makes unexpected guests row hard to hell. In your case, the train will be the pet's home, and roflimo will shout at sharks and leeches.
Talisman
Dances, sings and generally improves the mood of you and the whole team in every possible way. In the colony, their relatives consider them useless and push them to the outskirts, and on your train he feels at home.
Engineer
Repairs what he can reach, if he is not too lazy.
Although my earner does not mine anything other than organic matter and scrap metal!
They also do not write how to distinguish them.
