We're going to Big Moose

Freddy Jones:
Okay gang, here's the plan. An hour of canoeing, two hours of fishing, followed by a half hour of swimming! Daphne Blake:
In... there? [cut to Little Moose Lake, which is extremely dirty and disgusting like a swamp] Freddy Jones:
Yep. Luke:
Hey, why don't we go up to Big Moose Lake? That lake is sweet. Freddy Jones:
Oh no, not Big Moose Lake. We can't go up there. Luke:
Why not? Freddy Jones:
Because Big Moose Lake is haunted. Shaggy Rogers:
[nervous]
I'm out. Velma Dinkley:
Wait a minute. How can a *lake* be haunted? Freddy Jones:
Many years ago, there was a camper named Neil Fisher. The other kids picked on him all the time, so he spent most of his days swimming in Big Moose Lake. In fact, he spent so much time in the water he grew gills and fins. He became the Fishman. And he haunts Big Moose Lake to this day. Shaggy Rogers:
Is that true? Velma Dinkley:
Of course not. He just doesn't want us to go to Big Moose Lake. Freddy Jones:
Guys, we've got a perfectly good lake right here. Daphne Blake:
[sternly]
We're going to Big Moose. Freddy Jones:
[defeated]
We're going to Big Moose
