Star's ship
No POV:
"So let me get this straight. For the past few decades or so. The High commission went out to find a replacement since Mewmens and monster believed that one of them killed me, My husband, and meteora? And that it broke the peace between the monsters and Mewmens." Eclipsa said trying to get a understanding of what happened while she was frozen. "Yeah and sorry that you got frozen by a Irken." Star said and adds "Don't worry, we'll stop him before he does anything." "Thank you." She said "So who is the traitor supposed to be?" Janna asked. "The traitor is High Commissioner Gre." Eclipsa answered. "What?! He's the Irken! Aw man. I liked him." Star said and sadness. "We were all been a fool ever since me and the commission made him a commissioner." Eclipsa said. "So why are we going to Earth when he's on Mewni?" Janna asked. "For one thing, we need someone to look after Meteora since it will be dangerous... and that I also didn't bring my dimensional scissors since I thought ZiM wouldn't go to another dimension since he didn't had Minimoose with him." She told them. "So tell me about this ZiM and why were you following him?" Eclipsa asked Star who sighed. "It's a long story."
Elsewhere in space
Irken Armada
Inside the Massive
Two Tall Irken's were at the command deck watching as their forces were attacking a planet. The Tallest Red was slurping a smoothie while Tallest Purple was munching on Donuts. "It's been a great year." Red said "Yeah! It's been peaceful ever since we haven't heard of ZiM for a year." Purple said "Who?" Red asked "You know, ZiM." "The one that brings the donuts?" "No, that's Invader JiM. I mean ZiM!" "Ooh!!! Right, ZiM! Man I totally forgot about him." Red said as he laughs. "Yeah, boy was it a good thing that we banished him." Purple said as he joins in with the laughter. "Sir, we receiving a transmission." A Irken said as the Tallest calms down from laughter.

"My Tallest, you'll be proud to know that the plans for sending Mewni next to Earth is fixing to go as plan in a few minutes and I can't wait for your arrival." ZiM said. "ZiM!? We thought you were Dead!" Red said in surprise.

(Please note that the video is two minutes of ZiM doing the dance on a loop from Enter the Florpus but it starts when he says could a dead ZiM do this and starts dancing. You can stop whenever you want.)
"Anyway, I'll be looking forward for your arrival." ZiM said which confused the Tallest. "What are you taking about?" Purple said "Your arrival. You sent me a plan last year to have Mewni near Earth while you gathered a large force so you can attack bot the planets." ZiM told them. "But... we never sent a message for that?" Red said in confusion. "I'm sorry. But what?" ZiM said in confusion. "Yeah! We're currently invading a planet right now." Purple told him. "And why would we even gather a large force when we're already have a large force?" Red added. "Uh... I'll call you back." ZiM said as the transmission ended.
Mewni
Butterfly Castle
Moon POV:
It had been a year since I have been searching for the traitor and I even hired a Irken that Star ran with last year name Tak. I offered her a chance to redeem herself if she helped me in secret and that I would release her. She agreed and has been helping me trying to figure out who it is. Currently I was in the board room with the high commission minus Gre who told us to be here. "So does anyone know why Gre told us to be here?" Rhombus asked. "No clue." Prime said "It must be important if he wanted us all to be here." Hekapoo said. "Baa." Lekmet said "I agree. He is a mystery." Rhombus said as I was sitting waiting for Gre to be here. I then notice a purple light wave spreading all over Mewni for some reason. "What is that purple wave?" I asked as the commission looked out the window to see the wave as it covers the castle. "What's going on!?" Hekapoo said in confusion.

Above Mewni
Minimoose was blasting a purple beam all over the planet and once it had spread all over the planet Minimoose then starts shining a blinding white light which minimoose and the planet disappeared from where Mewni used to be.
ZiM POV:
I was frequently trying to contact Minimoose to cancel the order because I learned that the Tallest weren't the ones who asked me to do this. But I saw the flash from the sky and I saw Mewni orbiting close to Earth. "Ok... it could be worse." I said as I was outside and all the puny Humans were looking in the sky in confusion and amazement. "What's going on!?" I heard Marco said as he ran out. "Is this your fault ZiM!?" Marco demanded as I saw dozen of Ships orbiting Mewni and some heading here. "That can't be good." I said as the ships were now in Earths orbit and I saw that they were Irken ships but they had the symbol crossed out which means that they were rogue Irken's. "Attention, people of Earth! There is no need to worry! We are not invading Earth. But at this time the planet is under lockdown until the invasion of Mewni and the end of the Irken Empire is over. Please remain on Earth and do not get involve or else we will invade Earth." Someone said. "I'm gonna guess that your not with them." Marco said. "Yep." I said "So did you brought Mewni near Earth or was it them?" He asked me. "Them! It was totally them!" I said quickly as Minimoose floats next to me. "Wait? If your here then where's Star!?" He demanded. "Somewhere in space. I lost her when Minimoose came to get me." I told him. "We need to find her? She left her scissors-" I tune him out when I turned to Minimoose. "GIR! Get out here!" I yelled as GIR walked out without his disguise. "Oh, I should probably take off mine." I said as I took off my disguise. "Anyway, Minimoose I need you to teleport me and GIR to Mewni." I told him. "Nyah?" "I need you to stay here and warm the Tallest while Me and GIR handle the Leader so that when the Tallest arrive to destroy the Rogue invaders and then invade Mewni and Earth. That's when I will successfully completed my mission and I am the greatest invader that has ever lived!" I said as he opens a portal and me and GIR walked in to show this leader of this puny force that ZiM is the greatest invader the Tallest has ever sent.
