Replace Mei Prescott, Agnes Crumplebottom and Father winter

With trait cheats (which require testingcheats to be on).

First you have to create a sim that will replace them. Afterwards, move them in a lot and give them the final customizations (skills etc). Afterward, equip the required trait and careers and then evict them.

The cheat for the principal:

traits.equip_trait trait_Hidden_HighSchool_NPC_Principle

Principal has no special career required, so feel free to put them in the Education career in Discover University.

The cheats for Agnes Crumplebottom:

traits.equip_trait trait_Hidden_CottageWorld_NPC_AgnesCrumplebottom
careers.add_career career_Adult_CottageWorld_NPC_GardenShopOwner

The cheats for Father Winter:

traits.equip_trait trait_HolidayTradition_FatherWinter
careers.add_career career_Adult_NPC_FatherWinter

I have a lot of issues with the Highschool Years pack in general, it's just a little frustrating. The gameplay at school just isn't fun at all, and the principal just doesn't have the right vibe. Father Winter on the other hand isn't too bad, but when I have kids with him in the occult baby challenge, they get that special trait called 'Father Winters Baby' and they get special traits, but the trait barely does anything! I would really like to have a little more gameplay there. One of my favorite things about the Sulani Island Elementals is when you have a kid with them they have the "Sulani Mana" trait, and they can assist with plants and make firebombs! Give you, I don't think Father Winter's baby needs firebombs, but still, a little extra fun would be a nice addition.

Thank you so much! Are these the only 4 important NPC that I need to replace for sure, or there is others

I'm no expert, but I think the 'others' depends on what packs you have.

There is a mermaid in Sulani, don't remember her name at the moment, but shi is friend to one of my teenage Sims. There is a group of friend sI was planning to have them go to high school together then university. But when I tracked this Sims down I discovered she was a mermaid and had no family.
