METAMORPHOSIS

CAS Challenge | April 2025

April is the month of spring transformation, and in this month-long CAS challenge, you will have one Sim go through different phases in a transformative journey. This allows you to tell a visual story across the entire month, watching your Sim age throughout. They will age in steps, going through metamorphosis.

This challenge brings plenty of customizability and a bit of a new angle to the regular CAS challenges.

RULES

Maintain core facial features throughout all transformations while showing appropriate aging.

Consider writing a brief description for each day's creation to enhance the narrative of your Sim's life journey. This is optional! Do it only if you enjoy it.

Use any clothing, hair, or accessories available to you (base game or custom content) to express your Sim's transformation.

You do not have to finish every day. Do the days you find interesting and fun!

I encourage sharing your creations—whether it's every day or just a few—but it's completely up to you!

If you choose to share, please tag me (@HelloGreta / @LeebLeefuhLurv) or use the hashtag #MetamorphosisCasChallenge because I would love to see what you create!

WEEK ONE

Teen Years - Establishing Identity

Day 1: Create your Sim as a teen in their most authentic form. Establish their core features and personality by giving them traits and likes/dislikes. These core features will remain recognizable throughout their transformation journey.

Day 2: Establish your Sim’s earliest passion or interest. Show this through their appearance and style.

Day 3: How does your Sim present themselves at school? Create their typical school attire or uniform.

Day 4: Show how your Sim’s appearance changes when they meet their closest friends. What elements did they adopt from their friends?

Day 5: Dress your Sim for an important family celebration or tradition.

Day 6: Show what your Sim prefers wearing on weekends when they are free to express themselves.

Day 7: Dress your Sim as they imagine their future self! What do they think their young adult life is going to look like?

WEEK TWO

Young Adulthood - Finding Independence

Day 8: Age your Sim up to young adult. Dress them in an outfit they would wear when moving into their first independent living situation.

Day 10: Show how your Sim's style evolves as they form new friendships and connections.

Day 11: Show what your Sim wears on their first date as a young adult.

Day 14: Design your Sim an outfit for an important life celebration or achievement during their young adult years.

WEEK THREE

Adulthood - Settling & Growth

Day 15: Age up your Sim to adulthood. Create them as their more settled and established adult self.

Day 16: Show what your Sim looks like as they advance in their career or change directions.

Day 17: How have the stresses and challenges of adult life affected your Sim’s appearance?

Day 18: Show your Sim during a reflective period—when they ponder their life choices and directions.

Day 19: Show what your Sim looks like as they rediscover or pursue an old passion they may have set aside during their busy adult years.

Day 20: Show how your Sim’s health focus has influenced their appearance in middle adulthood.

Day 21: Show your Sim when they are ready to start a family—whether that means having a child, adopting, or getting a pet.

WEEK FOUR

Elder Years - Wisdom & Legacy

Day 22: Age up your Sim to elder. Show how they are embracing their elder years.

Day 23: Show how your Sim's appearance reflects the wisdom and experience gained throughout life.

Day 24: Show your Sim in an outfit for an important family gathering as an elder.

Day 25: Create an outfit your Sim would wear when enjoying their preferred retirement leisure activities.

Day 26: Show your Sim dressed in a style that reminds them of an important period from their earlier life.

Day 27: Show how your Sim is continuing to evolve and grow through their outfit.

Day 28: For the final day, create your Sim in an outfit that incorporates elements from throughout their life journey—symbolizing the complete metamorphosis they’ve undergone!

Happy Playing!!

☆ CAS Challenge: Create-A-Plant ☆

ANOTHER CAS CHALLENGE, LORD FORGIVE ME

This idea came from my discord server again where we talked about different kinds of plantsims, and then I thought: "What the hell, why not?" So here's a new challenge that's a little more simple than the rest I've made! Grab your D20s and D8s and just make a plantsim using whatever in-game plant you got! There's 2 dice to use this time given there's 28 options rather than 20!

If you do not own a physical d20 and d8, you can use this premade set to roll here!

As per usual, make sure to use the tag #createaplantcas so I can see all your little plants! Bonus points if you guys think of stories as usual, I would never say no to a good story to accompany my meal.

Day 18: Pop Culture Reference: Bella Goth as Morticia Addams🌹

[innisgreens]

hello, little doves!! 🕊️ to celebrate the announcement / release of THE SIMS 4: ENCHANTED BY NATURE and the long-awaited fairy occult type (i’m very much hoping and assuming), i’ve created my very first challenge — a whimsical, fairy-themed CAS challenge!

i’ve kept it short and sweet with seven prompts, and i’ve also included some vague visualizers for each for anyone who’d like a little extra inspo — but of course, feel free to go in whatever direction the prompt takes you!

𖡼.𖤣𖥧 woodland whimsy — a fairy cas challenge 𖡼.𖤣𖥧

one — dewdrop whisperer

a visualizer, if needed: soft petals, early light, mist-kissed lashes, bleary eyes, fresh fawn tracks, the hush before birdsong, forgotten earl grey tea left to cool, wild peony, young clover, sweet birch sap.

two — mushroom guardian

a visualizer, if needed: damp moss underfoot, warm soil, toadstools, a log fallen across a bog, iridescent beetle shells, the low thrum of the forest, crackling underbrush, frogs croaking in a shaded hollow, spiced cedar, moss-covered bark, black pepper, dried sage.

three — storm sprite

a visualizer, if needed: wild wind, static on the skin, the sharp bite of ozone, blades of grass, petrichor, a sky split in two, crushed violets, wild mint, windchimes, laughter on the wind, the flutter of startled birds.

four — moonlight trickster

a visualizer, if needed: a silver grin, a firefly trail, a giggle at a campfire, full moonbeams, cricket symphonies, night-blooming jasmine, smoked vanilla, star anise, plum juice.

five — keeper of the wild garden

a visualizer, if needed: smoked rosemary, a whispered secret, wildflower honey, the shimmer of a bee’s wing, berry-stained fingers, sun-warmed thyme, rosehip tea, bubbling brews on a stove, beeswax candles being lit.

six — crystal-winged regality

a visualizer, if needed: a sunbeam reflecting off a still pond, a monarch butterfly wing, the forest canopy, polished river stones, white amber, silver fir, the first frost, echoes through high trees.

seven — heir of lost things

a visualizer, if needed: forgotten buttons in the soil, a threadbare blanket, the damp earth beneath laundry hung to dry, a call from afar, chipped tea sets, the memories of last time, dried lavender, dusty rose, faded cardamom.

please tag me at @innisgreens or @cutietrait and use the #innisgreenscas tag so i can see your lovely creations!
