Extreme Opponents
Enter TIMETOLOSE at the magic codes screen and players can battle it out against opponents possessing extremely hard AI.
Adventure Two (Mirror Courses)
To access Adventure Two, you need to beat Wizpig in Future Funland and in the Overworld, get the TT and Wizpig amulets, and get golds in all four Trophy races.
Adventure Two is the same full set of courses from Adventure One, except they're all mirrored.
Code Access
To access all of the codes, you need to beat entire adventure (one). After beating Wizpig (in either the first or second race), you'll open up the credits. Watch the credits cut-scenes at the end and before it finishes, a code, like "FreeFruit" will appear. Go to Options and enter them into the Magic Code List.
Each time you beat Wizpig in either the first or second race, you will see a new code given. There are tons of them!
Free Fruit
By beating Wizpig the second time, and after watching the screen credits, at the end you'll see the password, "FreeFruit." Enter this in to start with 10 bananas.
Future Funland
To access Future Funland, the fifth world, you must place first in all of the Trophy Races and acquire the Wizpig Amulet. You don't need the TT amulet to access the fifth world, but once you're in Future Funland, you'll need it to race Wizpig again.
Drive to the Trophy sign (near the Lighthouse) and park in front in of it to gain access. You will see your character enter into the lighthouse, which then turns into a rocketship and blasts off to space.
TT Amulet
To access the TT room in World 5, containing the second race with Wizpig, you need to get all of the TT keys in each of the four worlds. The keys are in located in Ancient Lake, Dino Domain; Snowball Valley, Snowflake Mountain; Crescent Island, Sherbet Island; and Boulder Canyon, Dragon Forest.
