Send the letters
There is not much more to do. You can send a letter in Goomba Village to receive the Lucky Day Badges. If you’re still sleeping at Toad in Bibberberg City, you can get an ice potato and an Ultra Mushroom.
Get your diploma
Buy in the Badges lobby shop the last badges. Then you face the challenges in the dojo. The master is the only heavy opponent. But here again the tactic is to charge your jumps several laps and then flatten it within one lap. In the end, you will receive the diploma.
We have forgotten that!
You can still find a three Star Pieces that we didn’t go into before. For one, for a letter that you have to send on the shooting star path. On Lavalava Island on a coconut tree and in the Flower Fields. In the Rogueport Underground you will find a kind of elevator on the left. Fall through the gap to find the last Super Block.
On the way to the fortress
Once you reach Toad Town, refresh your energy and save it at the Toad Town Post Office. Go through the Stargate towards Star Haven. Arriving at the top of Star Haven, the 7 stars build a vehicle for you to get to Bowser. On the way to the vehicle on the Milky Way await opponents. 3x in total and you reach the atrium of the vehicle. Refresh your energies and save here at the bottom right. Go up here and get some mushrooms for safety in the lobby shop. Then go to the right and you will reach your vehicle. Here you also get the final move for Bowser – the star ray. At the end you reach the castle and the last chapter begins.
