Instructions
Power on the Wii and insert the MySims Kingdom disc. Start the game from the home menu and either continue or begin a game.
Walk up to the Sims around the Kingdom, other than Buddy and Lyndsay, and choose either "Be Nice" to receive Happy Essence, or "Be Mean" for Mean Essence.
Shake the trees you come across to gain their essences, and sometimes mana. Each of the different islands you come across will give you different essences, including Apple, Orange, Cherry, Cherry Blossom, Banana, Coconut, Pineapple, Musical Note, Rocket, Eyeball and Star.
Chopping down trees unlocks Wood essence. You can chop stumps to earn Dead Wood essence.
Jump on sofas to release both Spring and Simoleon essences.
Feed the animals for Organic essence. You'll come across rabbits, pigs and momma bear, all of whom will give you the essence.
Taking a bath will give you Happy and Superkelp essences, while you can get Happy and Angry essence from relaxing in the Hot Tub. Washing your hands gives you Octopus essence.
Prospecting can find you all kinds of essences. Hidden in the soil at the various mining areas around the Kingdom are Metal, Stone, Platinum, Gold, Silver, Bronze, Kaiserium, Electrobit, Diamond, Jade, Amethyst, Topaz, Onyx, Amber, Bone, Chocolate, 8-Ball, Pencil and Red Crayon essences. You can also find Bacon as a prospecting jackpot on Cowboy Island, and Alien as the jackpot on Spookane.
Fishing is another way to find essences, mostly of sea creatures: Angler, Gold Arowana, Bass, Batfish, Betta, Catfish, Crab, Electric Eel, Goby, Jellyfish, Koi, Marlin, Piranha, Plecostomus, Puffer, Robofish, Seahorse, Sea Turtle, Sea Urchin, Squid, Sunfish, Stingray, Tiny Shark and Ghost.
Find Angry essence from watching TV, using the bellows on the pizza oven, or running on a treadmill.
Peek inside the sarcophagus, hold a seance, or ride the rocket centrifuge to get Scary essence. Seances can also get you Voodoo Doll essence.
Eating at a Picnic can get you Apple and Cake essence. You can also find Cake essence from snacking in a refrigerator.
Watch a Hypnodisc to get 8-Ball, Eyeball and Star essence.
Pull weeds to gain their essences. Each island's weeds contain different essences, many of which you can find in other places. Explore the weeds on Cowby Junction to get Tire essence.
