SallyHey,
SallyI hear the Central Grassland is a great place to find
Marshmallow Nuts...
SallyAw, that's OK. Thanks anyway.
SallyOh! You found the Marshmallow Nuts already?
Can I have all 3 of 'em?
[Choice: Hand over / Keep for now]
SallyAll right! Now, do you think the bugs would like
a craftsman style or something more modern?
SallyYou wanna keep 'em? Why? Do you have your own
bug collection or something?
SallyI hope they don't just eat the nuts after I go
to all this trouble...
