You can get a huge amount of money (1000-4000) by going to the the stockmarket. Buy 1000 of the chepest shares like 6. That will cost you 6000 but it is 100% likely to go up within the next 12 hrs. Every 1 the share rises in you your shares will be worth 1000np more. Just sell them when you have made 2000np or more.
Grundos Gym is awsome. For every 5 obstacles you complete you complete a level. For every 5 Levels you complete you get a membership card. For every membership card you have when you complete a level you get a 1000np bonus for completing a level.
