With the edition of the Man-For-War beetle I thought that there could be a possibility of adding in an isopod Beetle. Specifically the giant isopod or Bathynomus Giganteus (its scientific name). I dont really have artistic ability so I cant draw examples but I still think that it would be cute.

For colors it could be....
White (common)
Brown (common)
Gray (uncommon)
Pastel (rare)
Albino (rare)

If anyone has already had this idea let me know. Also let me know if you have anything to add as this is just a thought and not finished or set in stone

What it looks like if anyones wondering....
