The appraisal reward for finding a seashell is ten pelagos.
- The image of the Seashell the player finds in-game seems to closely resemble the shell of a Periwinkle, a species of sea snail. Seeing as periwinkle shells are commonly used in decoration and for other aesthetic purposes, this particular shell seems to fall outside of the normal, as it is described in the player's Notebook as being "not particularly attractive".
