Little Tips N64

Play as TT:
You have to beat all of the tracks in the game in Time Challenge to get him. He will 
then appear as a playable on the character select screen. 

Play as Drumstick:
To play as Drumstick find all of the amulets, the WizPig and the TT amulets. Once 
you've done this, squash a frog with rooster feathers on his head in the central 
area (place with the red spot). 

Plane Trick:
When using the plane press "R" twice to flip and hold the control stick left or 
right to barrel roll. 

Space:
To go to Space, you must beat WizPig and get all of the Trophies and Amulets. Once 
you've done that, go to the sign by the lighthouse and honk at the sign near it. The 
lighthouse will transform into a rocket and blast you into space. 

Turbo Start :
As in so many N64 racing games, Diddy's got a Turbo Start (like Wave Race, Mario 
Kart 64). Just after the high-voiced announcer says "Get Ready" and the words start 
to fade, press the acceleration button (A). You'll get a mighty boost. The boost is 
more powerful and lasts longer the later you enact it. But be careful not to start 
it too late or it won't work at all. 

Zipper Boost:
For a blue flame boost off the zippers, let go of the acceleration right before the 
zipper. This will help you win the races dramatically.
