Phew, I managed to summarize Day 2. Here is what I concluded:
(S)tink
(N)eutral
(S)mell (G)ood
(S) Ike: The vast majority of the people argue that Ike, who wears heavy armor, thick clothing and carries a heavy sword while running, has a ridiculous strong scent of sweat. He is believed to lack deodorant and spend long periods of time without bathing. He also carries a strong smell of metal.
(N) Pokemon Trainer: The Pokemon trainer is believed to smell like a person that lives or spends a time with pets and animals. Generally, his scent is associated with pet food, animal smell, etc. He smells like a zoo. The Pokemon Trainer is an outdoors guy, too-- he is likely smell like the wilderness. But popular belief is that the Pokemon Trainer, susceptible to the stenches of animals and the outdoors, does not have a bad smell and is likely to be clean at most times. Some are just tempted to believe that he wears AXE or a similar fragrance.
(N) Yoshi: Yoshi has diverse beliefs. Many believe he has an intolerable scent associated with reptiles. Also, many have it that he has a fresh scent of fruit/candy depending on color. But just as many believe that Yoshi has a fairly subtle and tolerable scent.
The vast majority of opinions agree that Yoshi's breath is horrible or at least questionable. Oh, and quite a lot of people just believe that Yoshi smells like... poop...
Basically, Yoshi is Neutral in scent according to popular belief.

Of those three characters above, Yoshi was just the toughest to analyze. Based on the diverse opinions, I concluded that Yoshi has a neutral scent.
