To start it off in season 3 episode 10 krusty krab training video mr krabs was in a deep depression after the war.
what was the war exactly? apparently mr krabs fought in a war against primitive fish and other primitive sea creatures. You’re probably wondering what does have to do with pearls mother? well if you take a look inside mr krabs house you can see a picture of a whale next to a boat
so could that perhaps be pearls mother?! and as you can see she’s a primitive whale so could this mean in the war mr krabs killed pearls parents and took pearl in under the guilt and if you take another look in his house you could see a harpoon that he probably used to kill pearls mother
