Rep Missions
You need to have 100% relationships with the following people to get rep missions unlocked. Note: Make sure to collect piles of trash while they are still around. This is one of the requirements in the Artsies missions. They will disappear after awhile; act fast and do not recycle them until after unlocking the Artsies missions.

Luther Bigbucks: Richies mission.
Darius: Streeties mission.
Polly Nomial: Nerdies mission.
Roxanna Marie: Artsies mission.

Storage Areas
The following places are unlocked by reaching the maximum relationship with the following people.
1. Old broken down school bus near the thrift shop: 100% relationship with Giuseppi Mezzoalto.
2. Lost cave in Sim quarter: 100% relationship with Ewan Watahmee.
3. Garbage can near the entrance to Club Xizzle in Glasstown : 100% relationship with Phoebe Twiddle.
4. Projection booth (door behind the snack counter of the cinema in Glasstown): 100% relationship with Theresa Bullhorn.
5. Hole behind the poster in the jail: 100% relationship with Detective Dan De Mann.

Ninja Smoothies
After you return from the bayou and get arrested for running, talk to Detective Dan Mann until you have 100 relationship points with him. He will tell you that someone dug a tunnel and escaped from jail. Go back into the jail and notice that the poster that was there is now a tunnel. Between 6 a.m. to 7:30 a.m., a ninja will be in the tunnel and sell you smoothies that will give you skill points. One will give you 2,000 Simoleons.

How to Access Moon Base Zeta
Purchase a green meteorite off the Internet shopping. Then, with the meteorite still in you pocket, go to Sim Quarter and use the telephone booth. The moon base, where you can buy the Rocket Bed and Cheese Modulator, is now open. Note: Complete the first group of missions before attempting to open Moonbase Zeta. If it is still not accessible, then complete the secret missions and try again. Also, if it says "Phone home" when you use it, that means it worked and you can use it.
