I'm A Little Seed

(to the tune of "I'm a Little Teapot")

I'm a little seed, brown and flat,
I haven't got a front, and I haven't got a back.
When I get bigger, plant me in the earth,
I'll grow to be a tomato, while you play!

I'm a clever tomato, yes it's true

Here's an example of what I can do

I can change my color from green to red.

Just pluck me off and eat me up.
