Find Hidden Essence
Essence is hidden in a variety of locations in "MySims Kingdom" for you to collect. Find Moon Essence at the heliport and Dr. F's laboratory. Plant Essence is hidden at the stone pillar, the slide and the ski slope. Look in the curio shops and the snowman in the synth-o-matic for Bubble Essence. For Brown Essence, search the town hall and all flowers.
Collect the Perplexing Paw
When Dr. F asks you to collect a variety of parts for his project, locating the aptly named Perplexing Paw can be puzzling. You have to talk to an old woman in the north of Mangrove Forest. She will invite you to try the Kayaking minigame. Complete the game with a score good enough to earn a Bronze Medal award or better. You can attempt this minigame as much as you like. Give the woman your autograph afterward, and she will hand over the Perplexing Paw.
Finding the Evil Villain
Once you have collected every piece for the Mecha-Dog, take it outside for a demonstration. Follow the Mecha-Dog, and it will lead you to the zoo. When you enter the zoo, Mecha-Dog will be with an alligator. The alligator then smashes the cage, and a ladder appears. Climb the ladder and walk into the third section on the left side of the laboratory. The Evil Villain will be waiting there.
