DannyHey, buddy, think you can help me out? I brought
the kids here to look at the hot-air balloon...
Bummer of it is, that thing isn't going to fly anytime
soon. So what am I supposed to do with the kids?
I just know they're going to want to go swimming,
since we're right by the sea...
but I don't want anything nibbling on them!
That's a father's worst nightmare!
So be a buddy and defeat 8 Toothy Piranhas
for me, would ya? They're right around this area!
Of course I'll make it worth your while. How does
three Healing Powders and 2000 Dosh sound?
[Choice: Accept / Decline]
DannyI'll stay here with the kids and watch from a safe
distance as you take care of the dirty business, OK?
DannyI suppose I should pack up and head home, then.
This place isn't safe for the little ones!
DannyWhat moves! You knocked the stuffing out of those
nipping fish. Here. Take your reward!
DannyMy kids probably figure you're some kind of hero.
Me too, now that I think about it!
