The goal of this challenge is to "collect" every type of supernatural sim in your game by getting your sim to have one child of each supernatural type. The catch? All of the children must come from one (and only one) sim couple!

There are five total packs that each add a life state your Sim can be transformed into and/or and get a child from, which are:

- Get to Work (Aliens)
- Vampires
- Realm of Magic (Spellcasters)
- Island Living (Mermaids)
- Werewolves

You are not absolutely required to have all of these packs, and may mix and match as you like, but at least two are recommended!

Getting Started

- Create 1 YA Sim in CAS. He/she must be a ordinary human sim, but every other attribute is up to you.
- You may make your Sim's spouse in CAS also if you wish, but he/she cannot start with any sort of relationship towards your main sim and cannot start out living in the same household (must be moved in through normal gameplay).
- Place the main sim in a world/lot of your choosing. The only rule is that using the "On a Dark Ley Line" lot trait from Vampires is off limits.
- Set Lifespan to Normal.
- Your sim must get married and may only ever be married to that one sim.
- Your main sim must transform into each supernatural life state, then have a child with his/her spouse that is born as that life state. Rinse and repeat until you have them all!

General Rules

- Your sim must do whatever it takes to keep him/herself and his/her spouse alive and young enough to bear children. This can be done any way except through cheats.
- Your sim may never, under any circumstances, be unfaithful to his/her spouse. (You may make an exception for alien abduction pregnancies, as they are not considered cheating by the game, but this is up to your discretion.)
- You may only change the life state of your main sim through gameplay, and you cannot change the life state of any other sim (spouse/children/friends/etc.,) under any circumstance. (Your sim's spouse may be a supernatural if already made that way by the game, but his/her type cannot be changed).
- Obtaining supernatural children as science babies is off limits.
- For every child, your main sim must write a "scientific journal" (a book of any genre) about their species.

Life State Checklist

- Human
- Alien (Get to Work)
- Vampire
- Spellcaster (Realm of Magic)
- Mermaid (Island Living)
- Werewolf

Optional Rules

- For every child, one of your Sims must take a photograph or paint a portrait of them at the child stage (Or at all life stages up to young adult, if you prefer!)
- Your Sim may try to "collect" the other non-human Sim types available in the game by adding them to the household (I.E., building a Servo and asking a Ghost to move in). Bonus points if these Sims are/become part of the family tree!

And that's the challenge! I would love to hear any feedback, questions, ideas, and/or see your own sims' supernatural collections if you feel like sharing! Thanks for reading!
