Shrimpgiri

43 Nexomon list Shrimpgiri among their favourite foods (see Liked by). Fed to one of them in battle, it adds 15 to your capture chance; fed to any other, it adds 5. All food together adds 40 at most, and dragons, Legendary and Ultimate Nexomon count it for less, as the Nexomon page explains.

It also lures them: on the page of a Nexomon that likes it, in your Nexomon database, 5 of it start a lure.
