[It nightime at Butterfly castle.]
Moon: Bed' time, Star. Star: [washing plates] There you go, little buddy. Now everybody's all clean and ready for beddy-bye.
Moon: [enters the royal kitchen] Time to pack it in, Star— [yells and goes insane after seeing a spot on a plate]
Star: All ready, Mom. [takes her hairnet off] Just gotta brush my teeth and—
Moon: Star! [shows the plate with the spot to Star] What's is the meaning of this? [Star inspects it and then notices the spot]
Star: [screams] Spot, spot, spot!
Moon: That's right, a spot. You know the rule. Nobody leaves till...
Star: ...till everything's ship-shape. Don't worry, Mom, I'll get this plate cleaned up in a jiffy.
Moon Oh, and, uh.. lock up the castle when you're done.
Star: Lock up? Wait, Mom. Don't you remember what happened last time you left me here alone? [flashback to the castle on fire and shows Moon with tears in her eyes and cuts back to the present]
Moon: Should've never left you alone with a lit blow torch. But, since I've removed all the welding equipment from the premises, there's no-ho-ho chance of that happenin' again, right? Now, get to work.
Star: Aye-aye, Mom. La-la-la-la-la-la-la. [washes the plate but the spot is still on there] You're a tough little guy, aren't ya? [tries to clean it some more, creating steam through friction, but it's still not coming off] This means war. [Cut to Star trying to use a jackhammer, but it fails. Star falls to the floor and the overpowered jackhammer causes him to hit herself in the face repeatedly. She is then seen using a baseball bat and bangs the plate with it, and then a chainsaw to get it off by banging it on the plate with the blade, but nothing's working.]
Star: Wait here, please. [goes off and comes back riding a T-34 Tank, smashing through a safety poster featuring Moon.] Say good-night, dried on filth. Ready. Aim. Fire! [shoots a small pink sponge onto the plate then checks to see if the spot is gone and it's not]
Star: [frustrated] That is the last straw! I want you to remember... [crying] you made me do this! [spits on it and tries to rub it out but nothing happens. All of his attempts were fruitless] Naaah! [determined] I got to finish this. [Cut to Star in an army-like outfit. He speaks with an accent.]
Star: I'm afraid this is the last time we'll be meeting like this, my friend. Allow me to introduce you to... the SpotMaster 6000. [points to the SpotMaster 6000 behind her, which is a bizarre-looking cannon with a small microwave on top] Notice, the microwave-powered laser particle beam. Notice, the laser-guided high pressure water cannon. And notice, the little surprise I installed just for you. A specially woven metal alloy ingeniously combined with state of the art cleansing materials. [soap, mop, bucket, and other materials are combined with it] I call it... [pushes a button to show a ball of steel wool] ...steel wool! And it comes with... [a laser pops out of the wool ball] ...a laser! Any last words? [puts her ear near the plate] Mmm... I thought not. [jumps into the seat and puts on goggles] Power up! [Star turns on a switch on the control panel for the microwave-powered laser-particle beam. The microwave turns on, with a Corn rotating inside of it. A green laser is fired on the spot.]
Star: Water cannon... on! [turns it on, a blast of water is shooting at the plate] No effect. Steel wool laser... on! [turns it on. As the castle shakes, lights are shining out of it .]
Star: Okay, you asked for it. It may end life as we know it, but I am crossing the beams! [crosses the beams] More power! [does so, and it sends out 'sound'-like waves through the air, causing everything to look like it's wiggling. Moon hear noise coming from upstairs]
Moon: Hmm. I guess I better go see what Star up to.
Star: More power!
Moon: [sees a bunch of lasers and fireworks ] Oh, boy, this doesn't look good.
Star: More power!
Moon: Let's see what she's done this time. [Moon about to open the royal kitchen]
Star: Maximum power! [screams and pushes on maximum power. A huge blast wrecks the castle and a film of an atomic bomb exploding, which is actually a clip from Operation Crossroad, occurs. We now see the castle completely destroyed and then the Spot-Master 6000 disintegrates]
Moon: Oh, this time you've done it, Star. What've you got to say for yourself?
Star: [shows Moon the clean plate] The platter's all clean, Mom.
Moon: Oh, I'll clean your platter! [chases Star around the ruins of the castle] Come here, you!
