>>34686355The Blastoise line work well, too. Omastar and Carracosta would, if they were still alive. Cloyster, Slowbro, and Clamperl, as previously stated. Maybe... Kingler and Crawdaunt? I think I remember a picture of a Kingler with barnacles on its claws. Potentially Wailmer and Wailord.
I wonder if Toxapex and, perhaps something along the lines of Goldeen, could have a Clownfish/Sea Anemone relationship.
