well most of the outcomes are lose/gain forest fights or temporary buffs. How about you find a book written by choji and you find a soldierpill in it? or something that gives thintgs other than forest fights and atk buffs.
You open a book by Chouji...
(a) You find a piece of potato chip and you put it into your mouth. You were surprised that the chip still actually taste good. (gain some HP)
(b) You find a piece of potato chip and you put it into your mouth. You were choked by the awful taste of the spoiled chip. (lost some HP)
(c) You find a Chouji's Soldier Pill between the pages. You pop it into your mouth and walk away. (gain Chouji Soldier Pill buff)
(d) The book was all about food. It made you feel hungry. (Nothing)
(e) You found a secret ramen recipe! (take the recipe to Ichiraku & he will make you a special ramen that gives you 10-30 HP & attack buff for 15 rounds)
