Itchy and Scratchy cartoon
Collect all cards in the game then go to Lisa's level. Go to the Android's
Dungeon. Talk to the Comic Book Guy and buy a ticket for the cartoon. Then, go
to the Aztec Theater to watch the cartoon.

Ride an ATV or Quad
You can find an ATV or Quad to ride at the trailer park in Homer's and Marge's
levels. It is between two trailers at the far end. In Marge's level, go to the
trailer park short cut then go near the end of it. You will see a card floating
on the top of the trailer. Go on the left side of it and you will see a blue
ATV. Note: You can also ride the monorail in Apu's level.

Drive a monster truck
When on Apu's level, you can get a monster truck, Go to Springfield Stadium.
Directly next to the fountain is a green monster truck.

Drive Nightboat
When playing as Lisa, drive any car to the pier and look for the huge oil tanker
with a Globex sign on one side with a jump in front of it. Jump through the
Globex sign and drive to the top. Do not drive off. Park your car next to the
little gap/walkway on the left. Hop out and run up to the first set of crates.
Hop up to the very top and shimmy around the ledge. Inside the top crate is the
Nightboat.

Drive pink Cadillac
On level 6 with Bart, drive to Planet Hype (right at the beginning of the docks,
there is a revolving planet there) and go on the roof. The Pink Cadillac is
crashed into the front of the building in a little slot (facing the Squidport
sign). Fall off the front of Planet Hype, land on the Cadillac, get in, and
drive it.

Drive RC car
On the final level as Homer, drive to where the firetruck is a long ramp. As you
jump off it, look off to the side. You will see a little car with an antenna.
Slowly drive up past where the truck attaches to the ladder/ramp then drive fast
towards the building with mildew under the roof. You could also climb up the
other firetruck that is in the wreckage next to the building. Jump on the
ladder, then go up to the top of the firetruck. Next, go over the side of the
roof with the horizontal wood, then to the top of the roof with the RC car.

Drive a rocket car
In Homer's first level, drive to the power plant at the back of the town. Then,
drive through the power plant. Once you reach the end, keep going along the road
and on the left, in front of one of the big houses, you will find a blue and
white rocket car that you can drive around.

Multi-player racing game
Collect all the cards in one level to unlock the multi-player racing mini game.

Easy money
Get the rocket car in front of one of the mansions. After you drive around and
it gets destroyed, make sure you remember where you left it. Then, look for one
of the wrenches and get it while out of a car. The rocket car will now return.
You can smash it again and keep getting money as many times as desired. Look for
Buzz Cola boxes and Wasp cameras and destroy them. You will get about 30 coins
from each of them.

Decrease Hit and Run meter
When you are almost going to activate the Hit And Run, get out of your car and
borrow the first car you can find. Do not not drive one from the telephone.
Then, quickly get out and enter your car again. The Hit And Run meter will reach
zero.

Get a ride
Go to any level (Homer's first level recommended). Stand in the middle of the
road and when a car appears, jump onto its hood then jump again onto the roof.
It will take you all around the district.

Smoking tires
To have a very fast car, hold down the [Gas] + [Reverse] + [Brake] until the
smoke turns black and you see flames on bottom of your tires. This can only be
done with some cars. Release everything except [Gas] and you should go very
fast.

Seriously damaged car
On Homer's final levels, drive the 70's car to the yellow bridge that reads
"Evergreen Terrace and Power Plant". Speed out of the cemetery, drive onto the
bridge, and ram the car into the railings on the right-hand side the bridge to
get them merged into each other> Get out from the car and watch it fall. If it
does not fall, push it. Make sure it falls directly next to the bridge. It will
then appear from the purple water. Merge through the road completely damaged
almost exploded.

Alternate character reactions
When you buy different costumes, in each level the character you select will
react differently when you allow him or her to remain idle. For example,
choosing Bartman will have Bart jump up and fly around for a few seconds.
