One of the things I do before starting every game is filling my house with as permanent moodlet related objects as possible. Since there doesn't seem to be a guide on this, here is a list of permanent moodlets to keep your sims' moodlet meter at green or elated 24/7.
Decorated/Nicely Decorated/Beuatifully Decorated +10/+25/+40
One of the easiest moodlets to obtain. Simply fill your house with paintings and decor to get a +40 moodlet
Cozy Fire +5 to +17?
A flame fruit in the inventory will give a permanent +5 cozy fire moodlet. Fireplaces will give a higher cozy fire moodlet, and may be placed in every room for maximum effectiveness. However, since fireplaces are large and take up a lot of space, i prefer to only put them in certain rooms since they get in the way most of the time. Don't forget to get the 'Fireproof Homestead' to prevent your home from burning!
Music +20-40
Another easy moodlet to get. simply have music playing nearby to get this moodlet! A good tip is to carry a boombox around in your inventory so you can get this moodlet even when you're not at home.
Incense Holder +10-+30
There are 3 different incense that give out mood boost of +10 each, as well as an additional effect for each one. The effects are less stress, faster skill learning, and more successful romantic interactions. These moodlets can be obtained from each of the three locations from World Adventures. An easy way to get these is to use the buydebug cheat, and place them in a collection so you can buy them whenever
Stylin' +20
A permanent +20 moodlet that is awarded when you reach level 10 in the styling career. Although it takes a while to obtain, it is worth it for legacy sims or sims that you want to keep around forever with the never age potion.
Eternal Joy +25
A permanent +25 moodlet that is awarded when you wish for happiness from a genie in showtime. Genie lamps are quite easy to obtain through the PlasmaPunch Gyroscopic Conductor, although it may take around 5-10 tries to get one.
Faithful, Eternally Faithful +10-+20
Don't cheat with your partner for 12 or 20 days to obtain this moodlet
Wondrous Collection +10-+30
One of the hardest moodlets to obtain. Place a relic collection in the same room to obtain this moodlet. My personal favorite is the dangerous creature collection which gives a +25 moodlet with only four relics. Completeing the relic challenge will give this moodlet an additional 50%, however the challenge is pretty difficult to obtain and not really worth it.
Floor Hygienator +15 - +35?
One of the most overpowered and overlooked object in the game. The floor hygienator comes in three different scents, and can be placed anywhere on the ground, they can even be stacked on top of each other! Two of the scents will give a moodlet while the last one will restore your hygiene by a little bit. Although the moodlets are not permanent, the floor hygienator will refresh the moodlet everytime you walk over it, or every once in a while if you're standing on top of it. Place these floor hygineators over places your sims walk by or stand on top of for full effect. For example, place them under beds, under an art easel, at the front door, etc. Make sure to complete the "Masterful Inventory" challenge so these can't backfire. With the 'dirt defiant' LTR and a hygiene scent under your bed, you NEVER have to shower again!
Science Experiment
Another hard moodlet to obtain. First, you must be level 10 in the science career (you can quit after you reach level 10). Afterwards, the "perform science experiment" interaction will be unlocked. Now, you can use this interaction on almost every object! However, there may be a variety of results including mood boost, negative mood, set object on fire, object disappear, annoying noise. When you perform a science experiemnt, place the object outside so the whole house doesn't set on fire. Aim for "Success! Your experiment has imbued this object with a positive effect on anyone who walks by!" or "Success! Your experiment has imbued this object with a positive effect on anyone who uses it!". You can also get the additional aesthetic appeal, but uunncessary if you already ahve beuatifull decorated +40. You can undo the sciene experiment if you get the sonarific noise or negative moodlets, but there's not much you can do if the object disappears or sets on fire.
Beautiful Vista +10-+50
One of the best moodlets available! This moodlet is given to your sim anywhere on your lot! however, this moodlet only comes with certain lots, and It disappears when you try to move the home or lot. This moodlet is almost impossible to recreate but if anyone knows how or a mod to do this, please let me know.
Trait related moodlets
Loves Outdoor +20
Simply go outside! Great for fairies who sleep in fairy houses outside
Adventorous +10
Activates in tomb.
Loner +15
Be alone!
Additional Notes:
When you move out or change lots/houses, all the moodlets disappear! Make sure to take the flame fruit out and back into your inventory. The only way to reobtain the Stylist/Eternal Joy moodlet is to use a mod. For Faithful/Eternally faithful, wait another 12-20 days or use a mod. The only one of these moodlets that affects pets is the cozy fire from having a flame fruit in the inventory. Most of these should affect babies, toddlers, child, and teenagers as well. Although not permanent, ambrosia and the 7500 day spa package will give a +75 moodlet for 7 days. Let me know if there are additional permanent moodlets, especialy for pets!
