Somewhere, in an alternate universe...

There are seventy-five days to summer vacation,

Before school comes along just to end it.

So the annual problem for each generation

Is finding the best way to spend it.

Like maybe:

Crossing a tundra, giving tours on a rollercoaster,

or skiing down a mountain of beans.

Creating a system for remembering everything,

Or synchronizing submarines.

Meeting ghost patriots, taming tiger sharks,

Or making a self-driving car.

Cleaning a time machine, stretching a rubber tree,

Or whaling away on guitars!

As you can see, there's a whole lot of stuff to do,

Before the new grade this fall.

Phineas: C'mon Perry!

So stick with us, 'cause Phineas and Ferb are gonna do it aaaaaaaaaaaaaall!

And with Susanna's help, Phineas and Ferb are gonna do it aaaaaaaaaaaaaall!

Candace: Mo-om! Phineas and Ferb are making a spinoff!

Susanna: Seriously, Candace?
