And the next spoiler appetizer is here:
Spoiler:
Toriko and Komatsu visit the gourmet fortune teller Monchi, who gives them the hint to find their next ingredient, a special wine called "Ouzu". The duo then visit what seems to be some sort of booze-themed forest, and during their adventure they encounter a monster called an "Emerald Dragon". But wait! There seems to be someone riding atop the beast! Who is it!? Why it looks like.....
...It is! It's
KNOCKING MASTER JIROU!! 
Heh, it figures that he'd appear in a booze-themed location. However, the summary I read didn't detail whether or not Jirou aids the protagonists in locating that particular wine.
BTW, it sure would be cool if that dragon were his animal partner.....
