The two creatures cover their ears in pain as Jake stretched into a funnel and pressed against GOLB's chest. "I don't know if we can kill GOLB with music, P.B." Marceline doubted in worry as everyone continued singing. "We can dang well try!" Blaster responded over the walkie-talkie.

Will happen, happening, happened

Will happen, happening, happened

And there we are, again and again

'Cause you and I will always be back then

'Cause you and I will always be back then

You and I will always be back then

And so, you and I will always be best friends

"GOLB's opening!" Jake informed Princess Bubblegum and Marceline of a hole forming on GOLB as he reverted to his default dog form. Marceline drops Princess Bubblegum on the ground in front of GOLB with their friends and allies before flying towards GOLB.

They notice the hole shrinking as fast as it grew. "Slide faster, you ding dongs!" she yelled into the hole as it shrank. As it closed Finn slid onto Jake and Simon crashes into Marceline, causing them to fall down. Jake engulfs Finn and rolls into a ball as Marceline floated safely onto a rock with Simon when Blaster, his partners, and Bumblebee arrive via their van, hatchback, and muscle car vehicle forms before transforming into their robot modes. "Simon!" she said as she recognized Simon.

The ground shook beneath them as the Gumball Guardian stopped chasing the Duke of Nuts, Cinnamon Bun, and Lolly, and turned towards GOLB. The deity crosses its four eyes and emits a ray of energy that disintegrates the Gumball Guardian and the blue creature into nothing. "She did it! Yeah, Betty! Woo!" Finn cheered as he looked at GOLB while Normal Man looks at it with concern. GOLB distorts itself into a more terrifying black-and-white form. "What has she done…?" Normal Man said worriedly.

GOLB extends its hands towards the heroes, but a ribbon wraps around its head before the distortion dissipates, revealing a hybrid of GOLB and Betty, Simon's love. It stares down at them as they stare back in worry. "Aw great, I don't like this guy either!" Slime Princess pointed to GOLB. "No… Betty?" Simon mumbled with a sad tone. "Betty! Betty! Oh my Betty, my princess! Why did you…" Simon said as he ran towards GOLB before breaking into tears for Marceline to comfort him.

"You're back; it's what she wanted more than anything in the world." Marceline said as she hugged Simon. GOLB emits a low humming sound as it looked into the portal above it and flew into it, leaving Ooo. When the portal closed, Ice King's crown dropped from it and landed in front of Gunter. He quacked as he put the crown on his head. "Jump 'im! He's gonna wish to be all space villain!" Jake warned everyone.

"What?" N.E.P.T.R. said in confusion. "He's a big evil alien stuck in a penguin!" Jake reminded. "Oh, I see." N.E.P.T.R. said. Gunter distortedly quacks until he instantly morphs into a being similar to Ice King but with three red gems in the place of his upper face and crown, and bird-like feet while spouting nonsense. "Say, where's Gunter? The child that I love?" the being formerly known as Gunter wondered.

"Oh, nevermind, I think he wished to be Ice King." Jake noted. Out of nowhere, Gunter plays Ice King's drum set. "And for some drums, I guess. That's fine." Jake added. Optimus Prime and Grimlock slides down the face of the hills, damaged, scratched and sparking all over their metal bodies. "Hey Finn, I'm not doing so good." Fern said to Finn weakly as he climbed onto the rock he was standing on.

"Oh no…" Finn said as he knelt down to Fern. "Nah." he said before removing his hat, revealing long blond hair much like Finn's, but with red flowers growing from it. "I wish I could see the treehouse one more time." he continued. "Yeah dude, of course. Let's go there right now." Finn said as he held Fern's hand. "That's okay. Just promise to plant me there." Fern said before being taken away by the wind as blades of grass.

Finn cries as he opens his hand, revealing a large seed in the shape of a sword. Optimus Prime arrives at the scene holding Grimlock's proportionally giant arm over his shoulder. "It's… over…" he said weakly. "Who are you?" Finn asked the giant robot. "A friend." he said as he backed away into a green portal.

"Laters." Bumblebee said to Finn and company as Blaster and his partners walked through the portal before Broadside leaves the atmosphere in a flash. In another part of the canyon, the three other robots lie buried in the ground, dented and scratched. "What dive do you mates wanna go? Swerve's or Maccadam's?" the Formula robot asked the other two. "Maccadam's." they all replied simultaneously. "Nothin' but the good stuff." the blue robot commented with a southern accent.

Later that night at the Tree Fort ruins, Finn and Jake prepare to bury Fern's seed into the ground. "Feel ready?" Jake asked Finn. He places the seed in a small hole and covers it with dirt while smiling. Suddenly, a tree emerges from where Finn buried the seed, one branch having the Finn Sword driven through it. "Woah!" Jake said in awe at the growth.

"Hey, Finn." Princess Bubblegum greeted as she put her hand on his shoulder. Finn screams like a girl before lowering his pitch to not embarrass himself. "Excuse me. Hi, P.B." he said after standing up and facing Princess Bubblegum. "I just wanted to come say, thank you for disobeying my orders this morning. I'll see you tomorrow, okay?" she said before kissing Finn on the cheek. "See you tomorrow." Finn responded.

"You're getting tall. Good night." she noted before leaving. "Night, P.B." Jake waved her as she left. They next day, Finn and Jake lied on the grass with blades of grass in their mouths.
