Events are activities which unlock characters for the Sans/Papyrus Team or items for Chara Team. Events last for a short period of time. Usually, if you complete an event you will get a Badge. A badge will usually unlock a character or item. In order to complete events, you usually have to beat an enemy to obtain it. Most commonly, events are done as celebrations for holidays such as Christmas and Halloween, the former with Sansta and Krampus. The latter with Hardmode Insanity, Death, Pumpkin Sans, and Reaper Chara. Otherwise, but less commonly, events such as Rejuvenation will be done spontaneously. And sometimes, holidays won't get events, infamously occurring during April Fools 2023. You get to your enemy by talking to someone or entering somewhere. In order to know what characters or things you can unlock, see pages: Sans/Papyrus Team/ Weapons
