Monster Hunter 2 introduces the concept of time with Day and Night passages. The game also progresses into different seasons. Each season will dictate a monster's behavior and the materials you get from quests. During the Warm Season, carnivorous monsters like Wyverns are highly active, thus the ideal time for hunting. Come the Cold Season, monsters will become aggressive due to hunger and food shortages. This is a good time to obtain rare monster materials. Breeding Season is a time when Herbivorous monsters are most active and Carnivorous monsters are at their least. This particular season is best to gather materials from the field.

By paying a certain amount of zenny, you may directly switch over to next season by using your bed.

This village is the home to the famous Hero of Jumbo who was famous of his deed of slaying a Lunastra and most of all his weapon.
After reaching the mining cave to LV 3, you can pull out the sword that looks familiar to that Eternal Replica from the Lao-Shan Skull(not to confused with the one carried by Shen Gaoren.
In Monster Hunter Portable 3rd end credit, the Town, the Elder, and the wyerian lady make a cameo appearance.

In Monster Hunter 4 Ultimate, when speaking to the Grand Guru of Cathar to receive the Kushala Daora mission, he states that he received a letter from his brother, who once served as the chief of Jumbo Village. In the letter, the former chief warns of the Kushala Daora approaching Cathar, adding that the same dragon attacked Jumbo Village, but the village hunter was able to drive it off.
