Convincing West/Plesiosaur's third kill

Here's how convincing West and the beast third kill goes in The Plesiosaur.

Willy: We're telling you, sir! This beast isn't a shark!

Brian: It's a swimming reptile.

West: Look! It was only a shark attack, okay?

Dolphy: Sir, I find a tooth the size of a soda bottle stuck in the hull of a sunken ship last night, and it wasn't a shark's tooth!

West: Well, you don't have it! What is the creature?

Vinny: A Plesiosaurid. It's an Elasmosaurus!

Blackie: Sir, no one should go swimming at all!

Spongebob: Adam, if you open these beaches on the 4th of July it's like ringing a dinner bell!

Skyla: Yeah, if you swim in that water, just wait till it bites you in the flank!

Brian: West, we have to close the beach.

West: Brain, sick vandalism, that's what it is. If you're not happy with this stuff, rent a boat and go fishing.

Human Rainbow: Mr. West. What we are dealing here is a prehistoric, killing machine.

West: [laughs while walking to his car]

Blackie: He thinks it's funny!

Human Rarity: West, we can save it till August.

West: August? Listen here, young lady. This is gonna be one of the best summers we had in years! And there's nothing all of you can do to change my mind about it. [drives away]

Human Rarity: How rude!

Human Rainbow: That dumb jerk! [kicks in the sand]

Vinny: Now what?

Brian: [takes out his phone]

Blackie: What are you doing?

Brian: Making a phone call.

Spongebob: To who?

Brian: You'll see.

Human Pinkie: [excitedly] Are you ordering pizza?

Brian: No! [to the phone] Hi, there.

[We see people at the beach]

General Dedrich: Anything yet, men?

Leadwing: Nothing yet, sir!

General Dedrich: Keep on it. [into radio] Snipers, anything come up yet?

Pin-point: [on radio] Negative.

[West comes up to a family]

Father: Oh, hey Mr. West.

West: Why isn't your family in the water?

Father: Because, we just got here.

West: Doesn't matter, now get in that water.

Father: Yes, sir.

[he and his family and few other people followed and they got into the water.]

[the soldiers continue to look out for anything out of the ordinary]

Vinny: [sees a fin] [on radio] Dedrich! It's in the water!

General Dedrich: Men! The beast's been spotted!

Brian: Everybody out, now!

[everyone is now frantically trying to get out of the water as lifeguards blow their whistles]

[Then it revealed to be 2 colts with a toy fin]

Aftershock:

Colt #1: He made me do it! He talked me into it!

General Dedrich: WHAT KIND OF JOKE IS THIS?!

[Then the real Plesiosaur closes in on the CMC, Spike, and Button Mash]
