The lone Gumball Guardian and The Cake pin down the creature as the smaller robots shoot lasers from their arms. "We got him." Princess Bubblegum said in relief from afar. The yellow robot climbs onto the creature's face and drops a glowing red device into its mouth before jumping off. "Fire in the piehole!" he cried. All robots step back as the creature's chest swells and glows before exploding into blue flesh with its tongue flying into the Gumball Guardian's face, knocking it down in front of Princess Bubblegum.
"Help me, mom. I'm dirty nasty…" he said before mutating into a monstrous version of itself. "Princess, we came back to help!" a Banana Guard said as he and four others walk near the Gumball Guardian's hand before being grabbed by its tentacles. "Ah! Princess, help!" the Banana Guard pleaded as he was absorbed into the creature. "Ah!" Princess Bubblegum yelled as she shot jellybeans from her palm at the creature. The jellybeans do nothing as it regurgitates owls into the sky.
"Grimlock!" the yellow robot yelled over his comm. The Gumball Guardian creature turns around roars at the robot, only for it to be tackled by a giant spiky grey robot matching its height. "Yeah!" the yellow robot celebrated, throwing his fists in the air. The grey robot throws the creature in the direction of The Cake and starts shifting its body into that of a mechanical dinosaur. It lets out a roar into the sky, simultaneously breathing fire as a show of power.
"Sweet robot!" Flame Princess commented as she floated in the sky. "Who are you? Why did you come here?" Princess Bubblegum asked the yellow robot. "Lieutenant Bumblebee of the Autobots, and the dinosaur robot behind me is Grimlock. We're here to bring aid to the suckers who summoned this GOLB. The ship above you is the Cybertron Star Ship Broadside, or Broadside for short. Hi, Broadside!" Bumblebee explained before waving to the spaceship, still floating in the sky. "We appreciate the help… monster behind you!" Princess Bubblegum warned as she pointed to the blue creature reforming behind Bumblebee. He turns around but is knocked to pieces as the creature kicks him.
His head lands on the rock in front of Princess Bubblegum, seemingly inactive as his eyes stopped glowing. "Bumblebee!" she cried out. "Huh! What?!" he yelled as his head came back to life. "Don't worry about me! I'll be fine in no time." he reassured Princess Bubblegum as Grimlock charges into the blue monster. Bumblebee's head turns around and with two small wheels under his head, rolls off the rock and his body parts pull themselves magnetically towards his head as he grappled onto the Gumball Guardian with a hook from his mouth while it was fighting Flame Princess.
"Burn, burn, burn!" Flame Princess yelled as she fired a stream of flame at the Gumball Guardian's head to no effect. As Bumblebee swung towards the Gumball Guardian, he posed as if he was kicking, and did so right in the Gumball Guardian's eye. "Thanks robot guy!" Flame Princess said as she gave Bumblebee thumbs up as he stood on the Gumball Guardian's head. "'Name's Bumblebee, like the insect. Don't wear it out." he replied. The Gumball Guardian stood up abruptly, causing Bumblebee to fall down before slapping Flame Princess into the side of a cliff.
Marceline takes notice at the creature attempting to grab Flame Princess from the cliff and flies towards its eye to pull glowing goo from it in anger. The Cake and Grimlock in T-rex form are pushed back by the blue creature in front of the Gumball Guardian and are pinned down. Grimlock transforms into robot mode, but the blue creature lifts him up and throws him towards Optimus Prime and a squadron of jets flying towards GOLB. Grimlock crashes into three jets and takes out Optimus Prime's right wing before both come crashing down. "It's headed this way!" Princess Bubblegum observed as the creature walks towards them.
"I'll take down this beast, Fern's way!" Fern said before extending his bladed arm towards the creature's shoulder. He leaves a large gash in the creature, causing it to roar in pain. The creature swipes Fern away and looks down at Princess Bubblegum for her to fall backwards in fear. "No, no, no! No!" she cried before being crushed by the creature's giant paw as Marceline dug into the Gumball Guardian's eye.
"Bonnie!" Marceline cried out as she saw the creature crushing Princess Bubblegum. Her entire body glows red before a dark cloud engulf her and transforms her into a giant horned quadrupedal cloud creature with her face. She let out a roar before running off as the red, blue, and green robots fell out of the sky and crash landed onto the Gumball Guardian's head before it was tackled by The Cake. Marceline charges into the blue creature as Princess Bubblegum revealed to be alive under a pink force field. Marceline pushed the beast on its back before pummelling it into, quite literally, a pulp.
"Thanks." a face on what remains of the creature's front left leg said. Marceline reverted to her humanoid form and floated above the creature's remains while panting with exhaustion. "Marcy?" Princess Bubblegum said as she woke up and looked at Marceline. "You're okay!" Marceline said in relief as she flew to Princess Bubblegum. "My armour has an emergency…" Princess Bubblegum said before being interrupted by Marceline hugging her.
"You scared me…" "What?" "Even when we weren't talking I was so afraid something bad would happen to you and I wouldn't be there to protect you, and… *SIGHS* I don't wanna lose you again." Marceline said as she hugged Princess Bubblegum. "Hey, I'm a tough gum. Nothing never happening to me, never." Princess Bubblegum reassured Marceline. "I know, I'm… girl, you phrase that to weird!" Marceline responded in confusion. "I might have a concussion." Princess Bubblegum joked. They share a tender kiss, right before the ground started shaking.
