Slugpup

Slugpups are creatures added in the Downpour DLC. They are unlocked after completing the food quest and travelling to Journey's End, where they begin spawning in shelters in, , and s' campaigns. They rely almost entirely on the player for their survival.

Appearance
Slugpups are the juvenile versions of s, and are roughly half the size of an adult. Slugpups' bodies and eyes come in a variety of different colors, with green and yellow hues being the most common, and red and violet being the rarest.

Food
Slugpups need 2 food pips to hibernate, and 1 may be stored for the next cycle.

On the cycle a Slugpup is found, their food bar is not visible. Due to this, a common mistake is to not feed them during that cycle, resulting in the Slugpup starving and needing 3 pips of food the next cycle. A found Slugpup has an empty stomach, and 2 pips of food is enough for them to hibernate successfully.

Slugpups can eat anything that Survivor can eat, including all kinds of Centipedes.

Successfully hibernating with a Slugpup for grants passage progress towards The Mother. The amount depends on how many Slugpups are hibernated with.

Abilities & Behavior
Initially, Slugpups ignore the player until interacted with by means of grabbing or feeding. Upon being fed, Slugpups become friendly towards the player. Once sheltered with, a smaller food bar appears above the player's, indicating the Slugpup's hunger. Slugpups follow the player around unless distracted or given a stay command. Although Slugpups are capable of grabbing and eating food, such as on their own, the player may still need to feed them.

Slugpups can tug on the player and point, pick up and throw items like and jump over terrain. Upon entering a room with a hostile creature, like, any Slugpups that are not being held scatter. When captured, their food bar starts blinking red, alerting the player so they can save them. When killed, their food bar fades to a dull grey. While they cannot defend themselves when grabbed, if the player happens to be captured, they may throw spears and rubbish in an attempt to rescue them.

Every cycle, Slugpups have a chance to spawn in the current region inside a random. The spawn chance differs per region; it is relatively high in regions such as and  (50% and 40%, respectively), and lower in regions such as  and  (5% and 15%, respectively). However, when factoring in the number of shelters per region and general difficulty, is a recommended region to search for Slugpups, as there is a moderate 25% chance and traversing from shelter to shelter is relatively easy.

Utility
Slugpups can hold extra and other useful items for the player. Slugpups can also throw them to catch food and help the player escape when they are captured by a predator (e.g. a lizard). Slugpups deal the same amount of damage as, and can be surprisingly adept at killing or distracting creatures. When held, Slugpups may take hits for the Slugcat from Spears,  Dart Maggots, and  bites. On Expedition, their attacks count towards the player's challenges and score.

Training & Memory
Slugpups have memory of creature interactions and general player actions in-game. They typically watch and remember what the player does, which leads to them attempting to mimic them. Slugpups can learn to consider different creatures as threats, as well as learn to ignore others. Slugpups also learn to hunt and kill creatures that the player kills often. Movement, such as backflips and slides, can also be learnt by Slugpups.

Playing & Player Interaction
Slugpups can be given certain commands.
 * If the player jumps while crouched (down + jump), the Slugpup is told to stay in their current location.
 * A singular jump without directional inputs tells a Slugpup to play with the player. In this "play with me" mode, Slugpups stay closer to the player and pick up items more often.
 * A jump with the up direction held tells the Slugpup to stop playing with the player.

Idle Slugpups occasionally play with items and shuffle them around in their hands, as a form of fidgeting. They may also wiggle and jump around, and tug on the player's hand. Slugpups may also decide to nap while idle, laying down on the ground and closing their eyes.

Giving Slugpups items and gifts increases reputation. The player can also wiggle Slugpups around, which causes them to jump and move around slowly as if dizzy.

Food Preferences
Slugpups have unique food preferences. If a Slugpup likes a type of food, it dances around in joy to a level according to how much it likes the food. However, if a Slugpup dislikes a type of food, it closes its eyes in disgust and shakes slightly. If a Slugpup has a strong enough preference in either direction, they can also be stunned for a short moment, followed by the appropriate reaction.

Slugpup food preferences are impacted by personality traits, which can be modeled in the following table:

Personality
Slugpups have six personality traits that affect their behavior: sympathy, bravery, energy, nervousness, aggression, and dominance.

Out of these six, sympathy, bravery, and energy are hard-coded, and the other three traits are influenced by them.

Sympathy

Bravery

Energy

Nervousness

Aggression

Dominance

Variants & Attributes
Like other creatures in Rain World, Slugpups are vastly varied in appearance and attributes. These attributes, such as metabolism, stealth, balance, etc. affect their physical appearance and performance. This can be seen in the form of a Slugpup's color, wideness, speed, and lung capacity.

Slugpups have a wide range of color with multiple variables. Pups may come in either a pale or dark range of colors, which is determined in the game files by a variable called. Eye color is based on their body color, with darker Slugpups having pale eyes, and lighter Slugpups having dark-colored eyes.
