There are 26 Secret Seashells on Koholint Island, but only 20 are required to collect the L-2 Sword from Seashell Mansion. Bonus seashells are given there after collecting five shells and ten shells respectively, but only if Link goes there when he has precisely the right number - i.e., once Link has collected six seashells, he can no longer get the bonus seashell for collecting five. If Link collects the sword, any remaining seashells will disappear.
Secret Seashells can be found hidden all over Koholint. They are often found in chests, in grass cut down with the sword, under rocks lifted with the Power Bracelet, or recovered from the group with the shovel. Some have more unique methods of obtaining them, such as knocking them down from a tree with the Pegasus Boots, or receiving them as gifts in the Seashell Mansion. For a full list of locations, see Link's Awakening Secret Seashells (Game Boy).
