There is if you have an action replay, sort of. It gives you all of the course stars, which is 120.
Get action replay while you have all 150 stars. Use the action replay code: CUSTOM LEVEL. Talk to one of the Toads. He will give you a star!!!
Get all 150 stars
When you get 150 star you go outside with luigi and go to the cannon, then go on top of the castle and get the rabbit
Collect all 120 stars and go to the cannon outside. If you are playing super Mario 64 ds get all 150 stars and go to the cannon outside.
