Mobs

Mob is a general term for animals and monsters that move autonomously in the game, excluding friendly creatures such as livestock and NPCs. Under the game's default settings, players can attack mobs, and some types of mobs fight back or attack first.
Mob has HP just like the player character, and when its HP reaches zero, the mob collapses in place and materials can be obtained from the corpse.
Specific mob information can be found by category at the links below.
== Aggressiveness ==
Some mobs are aggressive and some do not fight back at all. Among the aggressive mobs, there are two types: those that attack players as soon as they see them, and those that fight back only if they are harmed. The "Aggressiveness" portion of each category article is listed in the three categories of "Strong," "Weak," and "None," in the order described above.
== Floating ==
Mobs marked [floating] in the notes section are ineffective in Defence Systems that affect only the ground surface. Spike tiles are an example. Be careful. Floating mobs do not come over rivers or buildings, so don't worry about that.
== Climate & Seasons ==
Each mobs has its own time of day, climate, and season of activity. Mob respawn from its nest, described below, is also linked to this activity time. If there is a nest and you cannot find that mob, you may want to check the hours of activity.
== Nest and mob respawning ==
Mobs that appear on the island field basically spawn with base objects called "Nest". VISM mobs do not respawn when switching screens or passing time, as in other games. Instead, mobs spawn from the nests. Once you have defeated the mobs near you and destroyed their nest, there will be no more mobs from the area permanently. However, if there are mobs around you when you attack a nest, the mobs will attack the player, so be careful when destroying the nest.
Wildlife that disappear in winter or mobs that only appear during certain seasons will resume spawning from their nests when it is time for them to be active.
However, as for the mobs that spawn in the underground caves and the Blood Moon Raid, they do not have nests and so do not respawn.
=== Nest containment capacity ===
Some types of mob nests contain mobs (e.g., beehive). When attacking a nest assuming that there are no mobs around, mobs may pop out of the nest. You should check your own status before trying to destroy the nest. If the "Aggressiveness" item in the mob list of each category article is not "None" and there is a number in the "Nest capacity", there is a danger.
=== Nest spawining ===
After the game begins, nests rarely spawn on the field. In such cases, a message will appear when the player is asleep, saying "A rare creature has been newly found on your island."
== Change with the game difficulty setting ==
The Game Difficulty Setting affects the player's attack and defense values, but it also changes the types of mobs and their nests that spawn on the field at the start of the game. You should read the article to learn more, but as a general rule, as the difficulty setting increases, the probability of beneficial mobs and their nests on the field decreases.
== Mob differences in the Blood Moon Raid ==
=== Status changes ===
HP and other stats of the same type mobs in the field and caves may be different during the Blood Moon Raid. If there is such a difference between regular and raid spawn, it is indicated in brackets within each category-specific article.
=== Drop items ===
Because of the large number of mobs spawning in the Blood Moon Raid, the item drop table is set up uniquely and the item drop rate is kept low. The items that drop are the same as the mobs found in the fields and caves.
