In Full Bloom

In Full Bloom is the hidden third mission of the Supermassive Galaxy in Super Mario Galaxy 2. It can be accessed in Huge Trouble with Big Wigglers and requires the player to cover a small planet in flowers.

Mission
The player must redo the Huge Trouble with Big Wigglers mission. They must follow the same path that they did in the first mission until they get to the Blooming Garden Planet. Rather than taking the Launch Star, the player must instead walk around the planet, making flowers appear in their trail. When all of the flowers have bloomed and the planet is completely covered in them, a Sproutle Vine sprouts, allowing Mario to get the Power Star.
