Toad

Toad is a very minor character in Super Luigi Country. He is Princess Peach's bodyguard and is very small. He is a reoccurring character in the Super Mario series.

Story
Toad has no connections to the story at all. He just stands next to Peach in the ending. For whatever reason, Toad claims that 'he's the best' right at the very end of the cutscene.

He doesn't seem very happy.

Trivia

 * It is unknown why the creators of Super Luigi County even put him in in the first place since he has very little importance. Maybe it was for the memes.
 * It could be implied that Toad was hiding under Peach's dress the whole time.
