Paper Mario/Chapter 3: The "Invincible" Tubba Blubba

Ghostly Presence
A Boo has been sighted in Mushroom Town near the forest. When you approach the forest, a Boo Butler appears and requests you come to the castle within the forest.

Forever More
Going through the forest, you have to keep an eye out for clues to get to the next section. Whenever something is different when going around the circle path, the closes exit is the one you should take. There are seven sections in all. The clues for each section, in order:
 * 1) Shaking bushes.
 * 2) Glowing eyes (as you are told by the dark figure in the forest).
 * 3) Flowers with large lips on them.
 * 4) A glowing face on a tree.
 * 5) 8 pairs of glowing mushrooms.
 * 6) Smiling flowers (that don't wither).
 * 7) A sign marks the correct exit.

PEACH: Bowser's Little Helper
Sneak out as Peach, and you will find Kammy Koopa trying to tell Bowser that Mario managed to defeat Tubba Blubba. When they spot you, they will ask what Mario hates most. If you want star points, say "hard enemies", but on the other hand, if you're low on items, you can select those and later in the chapter you will find the items by treasure chests.

Boss: Tubba Blubba
Tubba Blubba is the third servant of Bowser to guard a Star Spirit. He is a big blue monster that is half Koopa, half frog, and half kangaroo. He is known as "invincible" to the Boos because he ate too much Boos and he was never beaten. He was shown in Paper Mario. He was first shown in Gusty Gulch getting ready to eat a Boo named Stanley.
