You said that the Trolls weren't cannibalistic and that there were different kinds of grubs. I was always under the impression that all grubs were troll grubs and that they killed them en masse for food, cosmetics, etc. Do you have any examples or statements from the Trolls supporting your stance? Not saying your wrong, just wondering what I missed.
There are a couple different types of grubs.
Here we see an instance of a Grub used as a game
Sollux also has several grubs on his floor that he refers to as games
We can also assume there is also a type of Grub that is used as food, as we’ve heard of Grubsauce, Grubsteak, Grubloaf. We also see Grubpizza in Hiveswap as well as some unnamed grub food left out in Dammek’s hive.
And Then of course there’s Grubs as in Baby trolls and the Mother Grubs
