The Ultimate Emerald Sea Hare Beast is in the grassy area near Kamio Steel City. Pokémon Emerald Sea Hare Beast Catch is a water-attribute Pokémon that lives in wetlands as well as near seashores, and usually lives in the sea, so it is said that the Emerald Sea Hare Beast is in the grass near the city of Shen'o Steel, but as long as its skin does not dry out, it can also be active on land, and it will change its body's form depending on the environment of the place where it lives.

But it doesn't see a large difference in its abilities, though it has been suggested that its appearance changes due to the food it eats, though this remains unconfirmed. If the soft body is pressed hard enough, a mysterious purple liquid will ooze out, but the liquid is harmless.

Game setting

Pokémon Emeralds is set in the Toyoharu region, which is some distance away from its predecessor's Sekido and Joto regions, and is based on the Japanese island of Kyushu and Kyushu locales, however rotated by 90° compared to its prototype as Junichi Masuda felt that this move would result in a better gameplay balance.

The Toyo Edge region contains nine cities, six towns, and a number of attractions that are connected to each other by roads. Junichi Masuda declared that the name comes from the kanji 豊縁, meaning that the Fung Yuan region is a place of rich karma, denoting the theme of human-Pokémon relationships.
