After the events of Jumbo Josh eating the scepter after defeating Sir Dadadoo, you wake up to see Stinger Flynn lying on the hospital bed and Syringeon was standing in the corner, his 4 arms crossed in contemplation as you looked around you realized the photo of Banban looked like it was peeling

You got up and were about to peel it when Syringeon's voice cut in through the silence

Syringeon: "I don’t think that’s a good idea, who knows what could be behind it? Just leave it alone."

When you completely removed the Banban imagine you saw it... A blue version of Banban. Flumbo. The "Original Banban".

Syringeon: "You insolent human... Never play with the devil."

His voice was now cold as he appeared behind you, grabbing your wrist and spinning you to face him as he readied his drill hand

Syringeon: "DOCTOR'S ORDERS."

Everything then went black.

Later

When you awoke, you found yourself in a more secluded medical room that seemed untouched, aside from your remote to control your drone on the side. You stepped outside and navigated through the strange control room and when the blue doors opened a very beat up looking Banban stood at the door with a weak smile

Banban: "Oh... I was about to come get you..."

He says as he continues walking through the hall when suddenly Flumbo shows up and tackles Banban, they get into a fight that ends up with you and Flumbo taking a tumble into a hole as he looks to you

Flumbo: "Sorry about all that, but I just saved you. Banban cant be trusted"

Flumbo says, standing up as you both seemed to be in a weird play area... He continued speaking

Flumbo: "I first arrived here as a child, I was obviously scared but Banban had helped me adjust. Sure, he seemed friendly, but that all changed when Syringeon showed up... It was the first night I didn't get any sleep. Banban got me out of the room to show me a surprise, turns out it was a very hungry Ramamba. Nabnab had saved me, as he did many times with you, after I barely escaped with my life, Banban took me to this closet...Where he left me for years to rot"

Flumbo's face darkens as he stares at the wooden closet and the barrel of Givanium inside

Flumbo: "Now you may be wondering... Why am I telling you this? Well..."

Flumbo turns into his devil form with a sick grin

Flumbo: "B̸̡͗͆̆̕Ḛ̸̼̀̉̿̿̓͠C̸̈A̸͎̹͉̳̦̝͝U̷̞̣͕̽̾́̂̃S̶̈̄͜E̶̟̪̦͂ ̷͍͈̳̬̥̉̉̃̅͆͠ͅṄ̶̡̢̞͍̯Ȯ̶̟͉̰̹͕̦͑̀͠W̸͚͍̭̓͋̀ ̷̨̣͕͇̽Ǐ̷͉͖̎͝ͅṮ̴̻̄͑́̔Š̸͐͜ ̸̢̲͇͇̮̑̒Y̴̭̜̭̙̩̘̽͊͋̀O̶̻͌̃́̌̉̚U̵̦̜̤̠̼̝͌R̸̬̯̿̈̌͗ ̶͎͕̹̒́́͊͂͝Ṱ̸͚͎͑U̷͕̹̪̝̘͂͒͌͗̓͝R̶̰̲̀̒N̵͓̖͎̐̈́̄"

Flumbo says with a demonic voice, your terrified, you think you're gonna die, but then... He turns back to his normal form and laughs

Flumbo: "Hahah! Humans are so easy to scare! Sorry, but your face was priceless!"

Flumbo gives a kind smile

Flumbo: "I wouldn't hurt ya, I was just messin' around! But before you ask; yes, I do a devil form, just like Banban, except I can control it, and I'm not as controlled by bloodlust, but if I do end up getting a little to hungry... That wont end well..."

Flumbo says with a slightly darkened face, before he gives another smile

Flumbo: "But that wont happen! Your safe, for now."

Flumbo teases with the last part, but there is some truth to it
