Rock Lobsters are enemies in Mother 3. While they bear a resemblance to the Spineless Lobster found in the passage between Nippolyte's shack and Osohe Castle, the Rock Lobster is stronger and found on the sea floor between Cerulean Beach and Tanetane Island. Their glasses are similar to those of Teddy in EarthBound Beginnings.
It is very possible these enemies are a reference to the song "Rock Lobster" by the B52's.
