FREQUENTLY ASKED QUESTIONS ABOUT THIS QUEST

please read before asking

I have missed this quest! Why can’t I start it yet?
You cannot miss main quests they have to be completed in order. You need to complete all previous quests (list can be found here) and reach level 16 before you can start this quest

Can I complete this quest even though I have passed level 16?
Yes, you just need to complete all previous quests then this quest will start automatically

How do I send my sim to the park?
Go to the park and click on the whistle next to a sim who isn’t busy on the simtracker,this post explains more about the simtracker

How do I become friends with the alien?
Be nice to Osiris until your sim becomes friends with him, do this again to become best friends when you get that goal

What do you mean when you say a goal can be started early?
Any goal that you can normally do can be started early because you will have access to it and any goal that you can’t normally do you will have to wait until you get the goal to be able to complete it
The tip with this method is to put the sim doing that action early in a different house that you cannot go to until you get that goal or it will not work

I have spent S16,000 on items but the goal will not complete, why?
Make sure you are just buying items from the electronics section of buy mode

How do I negotiate with a sim eating plant?
You need to grow lettuce until it turns into a sim eating plant then when it has you will be able to negotiate with it

How do I get my sims to woohoo?
You need two sims who are partners to be able to get this interaction

I already have a world globe, do I have to buy another one?
Yes you do or you cannot complete this quest

I don’t have a stereo, where can I find one?
You can buy one from the electronics section

What do I get if I complete this quest in the time limit?
Snow outfits

What happens if I don’t complete in the time limit, can I still finish this quest?
Yes you have to finish it to unlock the snow park and weather machine before you can move onto the next quest

I didn’t complete in the time limit, can I restart the quest?
No, you cannot redo quests

Can I still get the prize if I don’t complete in the time limit?
No, the only way to get the limited time prizes is by completing the quest in the time limit

I don’t like this quest! Can I just skip it?
No, you have to complete this quest before you can move onto the next one

Some times are slightly different on my game, why is this?
Times may vary depending on the star rating of the item you are using, as the higher star rating an item has the quicker you will complete a goal

Some times are really off/ different goals show for me, why is this?
This will be because the quest has been updated recently, I try my best to keep these posts up to date but it is difficult as I cannot redo every quest each time the game is updated. If you notice any changes please let me know so I can update the post

  1. I finished the quest on time but I can’t find the outfits. Do I have to build the snow park to have them? 😥

      • Do u no if I can buy the globe ahead of time so I can “plot world domination” faster or will in not count and I have to wait till it says to buy a glob cause I don’t want to buy it early and spend $10000 on it and it not work?? Please help I’m at deep sleep and I need to know early so I can’t plot while sws sleeping

  2. The telescope in my park is set up in an area that my sim can’t walk in. What do I do? Everytime I tap on the telescope it gives me the little “I can’t go there” feet bubble

  3. I am also having the same problem. My sim can’t get to the telescope. I tried making her walk nearer the telescope but it’s still not working.

    • Of course you can, that is why I write these lists so you know what you can start early, all of the normal tasks you can do, e.g. End is nigh, bake croissants, read fine lit, warn simanity, movie marathon, deep sleep

      • Did you go to the house when the baking was finished before you got the goal, you need to wait until the goal appears, you can’t just leave the baking on the stove and click it when you get the goal as it completes before you click on the baked goods

  4. Hello there,

    ive already unlock the snow outfits. it seems i cant find in my store or wardrobe. currently im trying 2 find the key to unlock the door at snow park. Thanx

  5. Man my whole town is all senors within the week it sucks!!! I used to like this game now when all the senors die I’ll only get a new person every level when I’ll have over 10 houses empty how fun is that?

  6. Do I need to buy another world globe again even if I had one already? And can I do early the “plot world domination” task early?

  7. I’m level 15 and this quest hasn’t started. I have no other quests in my log and I have updated. I tried completely closing the game and going back in but it still hasn’t given me this quest. What do I do?

  8. Hi i did the an alien concept thing and i tisted the weather machine in my home but i cat find it in the park and i cant place it there and IT IS NOT SNOWING please help my i just want to know how to turn the park to a snow park and do i have to buy anything to make it snow in the park

  9. I can’t find the snow outfit for my preteen in the wardrobe….( I’ve browsed an adult wardrobe.) should I have to build a costume and swim store to get that? Will I get it even if I build the store after several months? ( I don’t have enough money to build it right now.)

    • Well I’ve definitely got the outfit in my wardrobe for preteens, maybe they have changed it in one of the recent updates?
      It might be in the store, and yes if it is there it would be there when you get around to building it

  10. I can’t find a snow outfit. Should I buy the machine first and change the weather into snow so that I can get it?

  11. I had an adult deep sleeping, and before the adult was done, my baby woke up from a four hour sleep. The goal was completed by the baby waking up!!!

  12. I just finished the alien concept quest and I have searched the park MULTIBLE times but I STILL can’t find the snow machine!:'(

  13. Ea is a stupid company. My Sims are
    dying off and it makes me so mad!!!
    I’m on lvl 30 and I only have 11 sims!
    Ea is going down after this update!

  14. Thanks for all the hard work you do to make our gaming experience even better! I’m just curious if others are as freaked out as me by the alien wandering through your sim’s house at all hours of the day and night? Taking a bath and he walks in the door…..EEK! LOL!

  15. Hi! I would love if u could answer my question. I’ve been searching all over. I want to buy the weather machine but I am a migraine sufferer and the lightening will bother me. Is there a way to set it so it won’t be set to lightening? Also, if I don’t like the weather machine can I stop it? Thanks!!

  16. I’m so confused… I never got to this quest after Sous Judgemental, is there something wrong with my sims? Actually I’ve been missing a few quests like the pre-teens one and etc.

  17. Has anyone else seen the UFO? I saw it once but haven’t seen it again. Does it do anything or is it just for show?

  18. Just asking, I’ve finished this quest ages ago but because it’s christmas time again and I want to make it snowy in my home, is it worth buying the weather machine for 70,000 simoleons??
