Greedy Monster is an Info Item in Xenoblade Chronicles 2. It can be obtained after Chapter 4 by speaking to Razzlydazzly in the Argentum Trade Guild, by purchasing it from the Informant shop at the Kedeigh Gate of Alba Cavanich in the Empire of Mor Ardain, or by purchasing it from the Informant shop at the Plaza of Reprieve of Garfont Village in the Kingdom of Uraya. After obtaining this information, there is a chance that the Gluttonous Marrin will appear when Salvaging near Chansagh Wastes in the Lower Level of Mor Ardain.
