Level 1 takes place in the Simpsons' own neighborhood, Evergreen Terrace.
The Cola Caper (Tutorial)
As you begin the game, Bart will explain to you how the basic controls work. If you don't want to listen to him, you can disable the tutorial with a button press or in the options menu.
Either way, talk to Marge to begin the mission. Someone ate every dessert in the house? Now Homer certainly wouldn't have done that, would he?
Drive to the Kwik-E-Mart and talk to Apu. Pick up the ice cream and cola, and this mission is complete. Of course it's easy, it's a tutorial mission. Don't worry, it gets harder.
S-M-R-T
Lisa forgot her science project! You must race Principal Skinner to the school and give Lisa her project back.
Talk to Marge at the Simpson house to begin the mission. Collect the science project, then get into your car and start driving to the school. Along the way, you'll meet Skinner's sedan. Take shortcuts to beat him -- the best shortcut to use is to take a right turn before you get to the Kwik-E-Mart, then go up the fire truck's ladder. You'll careen over the Krusty Burger and into first place.
If you decide to go for a more direct approach, then try bumping Skinner's car from the rear and forcing him to spin out.
Once you beat Skinner to the school, walk inside and talk to Lisa to give back the science project. Hey, where's the gall bladder?
