Play as Nabbit in Single-player
If you press ZR+ZL together as you start a level (or the B button, if you're using a Wii Remote), you'll be able to play as Nabbit in the single-player mode. Normally, he's only available when you are playing with friends.
To obtain all five file stars, you'll need to:
- Beat the last Bowser
- Find every normal and secret flag (there are 94 in all)
- Catch Nabbit when he appears in each of the first seven worlds
- Obtain every star coin in the standard 8 worlds
- Obtain all star coins in every world and level, including level 9 in Superstar Road
