- Keesha Franklin: Scum, tuna fish sandwich - scum, tuna fish sandwich. What's in a tuna fish sandwich, anyway?
- Keesha Franklin: I've got it; I've got the connection! What eats phytoplankton? Zooplankton! And what eats zooplankton? Little fish like anchovies!
- [a tuna is about to eat up the bus]
- Keesha Franklin: And what eats little fish like anchovies?
- [no answer from the class]
- Keesha Franklin: Well?
- Carlos Ramon, Phoebe Terese, Dorothy Ann, Ralphie Tennelli, Wanda Li, Tim Jamal, Arnold Perlstein: Tuna fish!
- [all scream as Keesha sees the tuna about to eat the bus, then she joins in]
- Wanda Li: This is it, Ralphie, the wave of our dreams!
- Ms. Valerie Frizzle: When we get back to the classroom, we will discuss our observations.
- Keesha Franklin: [watching Ms. Frizzle surf after the bus has transformed into a surfboard] Arnold, do you observe what I observe?
- Arnold Perlstein: She's hanging ten! There really is more to Ms. Frizzle than meets the eye.
- Keesha Franklin: So to wrap up our report, allow us to show you the artwork we've commissioned. An original "Tim".
- Arnold Perlstein: Here we have our recent experience: the ocean food chain. It works like this. Scum, or phytoplankton, are eaten by zooplankton, which are eaten by small fish like anchovies, which are eaten by big fish like tuna!
- Ms. Valerie Frizzle: And this class, is a *land* food chain.
- Tim Jamal: Yeah, a mouse eats grass seed.
- Wanda Li: A snake eats the mouse.
- Carlos Ramon: And the hawk eats the snake.
- Ralphie Tennelli: [presenting their "two beach things that go together" report to the class] Why the sun and dune grass go together, by us. All rights reserved.
- Phoebe Terese: Dune grass, like other plants, uses energy from the sun to make its own food. No sun, no dune grass.
- Ralphie Tennelli: No sun, no nothing!
