Plot
Four days after the incident at the bowling alley.

(Stew): So Dad... let me get this straight... you're a plumber?

(Dad): I was a plumber once... intergalactic police, basically. I learned about all sorts of species in the twenty years I served.

(Stew): Cool! So that's why you knew about all of these aliens? Oh, and thanks for letting me practice these past few days.

(Dad): Yes, that's why I know about those aliens. And you'll need the practice to survive. I'm not what I used to be, so you should find an actual ally. One that can really support you.

(Stew): But who would that be?

(Dad): Well, there's a guy I know, and he's only about two states away.

(Stew): Two states away?! That will take days to get there!

(Dad): I know, so I packed up the car with supplies.

(Stew): Wow Dad... how did you do all of that without me knowing?

(Dad): You were too busy trying out all of your aliens. Speaking of your aliens, how many have you tried out?

(Stew): All but two now. I really practiced with Ditto, he's my favorite.

(Dad): Okay. Well, time to finish packing.

(Stew): I'm gonna turn on the radio.

(Dad): Keep it on the news channel.

(Stew): Got it!

(Radio News): In recent events, it appears we are now rebuilding the bowling alley, and it should be done soon. Hopefully, you'll al- BREAKING NEWS! Some thugs have stolen money from the Vital Ka-Ching bank! They're on the corner of West Street, driving in their getaway car!

(Stew, turning off the radio): Dad...

(Dad): I know son. Go get 'em!

(Stew, turning the dial): I'll see you soon!

Stew transforms into XLR8

(XLR8): XLR8!

XLR8 speeds away.

(Dad): Go get 'em son...

Downtown West Street.

(XLR8): I've got them cornered!

(Thug 1): Get out of the way!

(XLR8): In your dreams!

Boop, boop, bweep.

(Stew): Oh no...

(Thug 1): A kid? Like he'll be able to stop us!

(Thug 2): Move kid!

(Stew):  Oh noooo!

Omnitrix suddenly recharges.

(Stew): That's faster than usual, but I'll take it!

Stew turns into first alien possible.

(Shellhead): Shellhead! What does this guy do?

The car is only a few feet in front of him.

(Shellhead): Ahhh!

Shellhead withdraws into his shell.

(Thugs 1 and 2): Nooooo!

Thugs crash into Shellhead.

(Shellhead, hearing a crash gets out of his shell): Hello? What happened?

Shellhead sees the crash right in front of him.

(Shellhead): Did I cause that? My shell must be my power! Only defense... oh well, it worked out. But until I find some kind of real attack, this guy is useless to me.

(Thugs 1 and 2): What the heck are you?

Thugs get out of car with their guns.

(Shellhead): Don't you even try to shoot me!

Shellhead rams one of them with his shell, knocking Thug 2 out.

(Shellhead): Sweet! I should've known defense was good for melee..

(Thug 1): You're a dead man, turtle, THING!

Thug 1 starts shooting at Shellhead.

(Shellhead, drawing into his shell): You can't hurt me like this!

Thug 1 runs out of ammo.

(Thug 1): Gah! I gotta reload!

(Shellhead): Not so fast!

Shellhead rams into Thug 1, knocking him out.

Beep, beep, bweep.

(Stew): Time to run!

Stew runs away as fast as possible, letting the cops take the Thugs in.

Earth's Orbit

(Hidden Voice): How many more resources do we need to execute plan seventeen point alpha five?

(Minion): It'll take another two weeks at most.

(Hidden Voice): Good... we'll need all the resources we can get.
