The Memorial Shell (一生の証?, lit.: "Proof of a Lifetime") is a treasure in Pikmin 2 and it is actually half of a scallop shell, with what appears to be a small pearl or water drop forming on the inside surface. It is found on sublevel 3 of the Citadel of Spiders and is completely buried in the ground, so White Pikmin are needed to dig it up. It likely forms the counterpiece to the Scrumptious Shell.
“I've observed several species of shell-dwelling creatures inhabiting the Perplexing Pool. One of these feisty beasts forms a spherical gem within the meaty depths of its shell. In a way, this gem could be considered this creature's lifework. I consider my children my life's work.”
“All that remains of a monster shellfish is a sparkle, the sole proof of its existence. Does this not make you want to treasure it?”
