Diddy Kong Racing DS

Adventure 2:
Complete the second Wizpig race in space and watch the credits. Adventure 2 will then be unlocked.

Hint: Opening the cracked wall:
At the start of the game, follow the track round until you go in a tunnel. In here, there is a cracked wall with a picture of Wizpig. Draw round Wizpig's head (ears included) and the wall should smash open. You must be quite accurate and it may take a few attempts.

Hint: Play as Drumstick:
Look for the mountain with the Frog Effigy. It is to the left of Wizpig's head. Use the stylus to pull back the frog and let go to release it. Try to launch it up to the Frog Effigy. When you do this successfully, a short intermission sequence will play and a new frog with a chicken head will jump out. Run this frog over to unlock Drumstick. His stats are:

Top Speed: 4/5
Handling: 2/5
Acceleration: 5/5

He is the best racer in the plane.

Hint: Play as Taj:
Collect all 47 balloons, have the full Wizpig Amulet, and get all gold trophies. After you have done this, go to Future Fun Land and start the final Wizpig Battle. Once you defeat Wizpig you will unlock Taj. His stats are:

Top Speed: 5/5
Handling: 1/5
Acceleration: 1/5

He is the best racer in the car, although his stats will make you think otherwise.

Hint: Play as T.T.:
Beat all of T.T's times in Time Trial mode with every vehicle. You must also have the full T.T. amulet. You will see his ghost when you start the Time Trial. You must beat this. Once you defeat his ghost in every level, with every vehicle (including the unlockables), T.T. will be playable. His stats are:

Top Speed: 5/5
Handling: 4/5
Acceleration: 5/5

He is the best racer in the hovercraft and is a very good, all-round racer in every vehicle.

Hint: Accessing Future Fun Land:
Once you get all the trophies and complete the sign, it will look as if the island is saved and the credits will roll. However, all is not completed. Go to the lighthouse at the beach and it will turn into a rocket. After the intermission sequence ends, drive into the portal of light where the lighthouse used to be. You will be teleported to a new world, Future Fun Land.

Hint: Ancient Lake: Secret key:
At the start of the Ancient Lake level, there will be a ramp on the right. Collect a blue balloon and boost up the ramp collecting the key.

Hint: Beach: Secret balloon:
Go down to the Beach where you join the dots. Instead of drawing a circle, draw a balloon. A secret balloon will appear. This may require a few attempts.

Hint: Beach: Easy coins:
When you go to the Beach, there should be a series of dots in the sand. Join them up into a circle. A number of coins will fall. Collect them all. Keep repeating this until it no longer accepts the dots joined up.

Hint: Beach: Cracks in the wall:
Go down to the beach and touch a coconut tree with your stylus. Pull one of the trees back and release it. You can make three cracks in the wall. Collect them quickly. Coins will appear which can quickly disappear after about ten seconds.

Hint: Boulder Canyon: Secret key:
Go across the drawbridge and hit the blue balloon and the little bell. You should now have a boost. Turn around and wait until the drawbridge is fully raised. Boost up it and you should now be sitting on a ledge with the key.

Hint: Crescent Island: Secret key:
Start the Crescent Island level and pass by the big river on your left. After this river, there will be a little lagoon. The key is in here.

Hint: Dino Domain: Loose Balloon:
On the road up to Dino Domain, there will be a balloon sitting there waiting to be collected.

Hint: Snowflake Mountian: Ice balloon:
On the way to Snowflake Mountain, to the right of the entrance will be a balloon in an Ice Block. Use the stylus to slide it all the way down the path and into the water. It will float all the way down the river and will be thawed out, waiting to be collected at the beach.

Hint: Snowball Valley: Secret key:
After passing through the Snowball valley and exiting the igloo tunnel, move through the Balloon row that you see. Go down the straightaway to the finish line. Then, hang a left just before the candy cane holding up the finish line banner. Move up the hill towards a picket fence, then turn right to find a small cubbyhole containing the key.

Hint: More effective turbo boosts:
You can get more effective turbo boosts by releasing A before you hit a zipper or by using a blue balloon. You will hear and see a difference.

Hint: T.T. Amulet:
Get all of the secret keys nd open all the doors with them. Defeat T.T. in all the tracks you create and you will gain a piece each time. Make the track shorter for a quicker win.

Hint: Wizpig Amulet:
Defeat the Bosses from each World twice (the first Battle and the Boss Rematch).

Hint: 100 Coins:
After defeat the Bosses the second time you can go back and try the Boss Touch Challenge. They are very difficult, especially the one at Dino Domainone.

Hint: Banjo series references:
The key in the Snowball Valley looks like the Ice Key from the Banjo series.

The Silver Coins look like the ones in Spiller's Harbor from Banjo-Kazooie: Grunty's Revenge
