Toad stars

Toad stars (or just plain Toads) are people inside the castle who you can talk to.

What makes them Special?
Unlike other Toads these Toads will (like all Toads) give you a inane tip. But however then will give you a star!

Where do I find them
They can be tricky to find due to all the Toads in the castle but I will sum them up here!
 * Near the entrance to the Hazy Maze Cave course. 
 * On the castle's second floor, under the stairs that lead to the Tick Tock Clock course. 
 * On the castle's third floor, just right of the big clock that leads to Tick Tock Clock. 

Trivia

 * There speech changes depending on if your controlling Mario,Yoshi,Luigi or Wario
