Terrebore(Based on an animal, dual type, might need to sound the name out phonetically)
and unrelated to the above
Shishieon(related to an official Pokemon)
Is terrebore a pig(Bore sounds like boar) and ground type(No idea about other type)? I think shishieon is an eeveelution(eon at the end) and is it bug type (heard about a japanese guardian of the forest,shishigama)?
You got the name and first typing for Terrebore correct, and Shishieon is an eeveelution. You still need the second type for Terrebore and the type for Shishieon(It's not bug)
