Interesting result. So it's either a Bug/Water type or a Ice/Water type. That's not gonna be a very long list.
Bug/Water:
-Surskit
-Dewpider/Araquanid
-Wimpod/Golisopod
Ice/Water:
-Dewgong
-Cloyster
-Lapras
-Spheal/Sealeo/Walrein
-Arctovish
-Iron Bundle
I know from back when I did Golisopod that that line is an Athropod.
Apparently Arachnids are Arthropods too, so could be Dewpider/Araquanid too.
Surskit just says it's an insectoid. Probably counts too then.
Can rule out the Ice/Water types due to not being arthropods.
So should be 5 left.... can't really think of a clean question to stack with the evo question above.
Does this line's evolution occur at level 22 ?
Which would either rule out or lock in the Golisopod line.
