Hunger is one of the hidden values all slimes have which determines which standard facial expression they will assume, including in relation to their agitation values. Eating food lowers a slime's agitation, so keeping a slime fed is the most guaranteed way to avoid negative behaviours from occurring. Slimes do not die from not being fed for extended periods of time, and unlike Agitation, there are no external modifiers for slowing down Hunger.
|The Slime is fully fed and happy, and will not seek out food.|
|Its face will decay to "Happy" approximately 6 hours after its last feed, and will start seeking food.|
|The slime has gone another 12 hours - or 18 overall - without food, and decayed to "Hungry".
Hungry slimes may have already started performing their negative behaviors - or passive behaviors more often, if applicable.
|The slime has gone 29 hours without food, and is agitated.
Agitated slimes will perform their negative behaviors - or passive behaviors significantly more often, if applicable.
A slime can eat when its hunger value has reached or exceeded 33.33%. Unless consuming Spicy Tofu, in which case hunger reduction is 0% and can be done regardless of hunger value, pure slimes have their hunger reduce by 33.33% when eating, while Largos have it reduce by 66.66%. Hunger can not fall below 0%, and any time it would by eating, it is set to 0% instead. Feral Slimes will always eat food regardless of hunger, and will obey their own hunger value once they have been calmed; so a fully fed feral slime will eat to calm down, but not immediately after.
- A feral slime will always eat regardless of hunger, and a Hunter Largo can go feral when highly agitated. It is possible to force them to go feral by shooting Fire Slimes at them, then feeding them again to calm them down to produce more plorts.
- Gold Slimes and Lucky Slimes are susceptible to hunger and agitation like any other slime. Due to the nature of their rarity and despawning mechanics, this does not normally come into play under normal circumstances.
- Hungry and Agitated slimes will not show the characteristic scared face of a slime experiencing Fear, but will still try to flee the source of their Fear.
