Title: Episode 78: Kirby and the Gang Do a Ritual*

[The scene opens with Kirby, Tiff, Tuff, the Dream Friends, and the Dream Squad gathered in a mystical, dimly lit room. They are surrounded by arcane symbols and candles. The air is thick with anticipation.]

Tiff* "Okay, everyone, be sure our hearts are in unity. This ritual should help protect our worlds from any looming threats."

Magolor (whispering to Marx)* "You think this is going to work?"

Marx (grinning mischievously)* "With Kirby here? Anything's possible."

[Everyone joins hands, focusing intensely. Suddenly, Kirby's eyes glow a stark white, and chains burst from his chest, wrapping around everyone except Marx. Chaos ensues.*

Tuff* "Kirby! What's happening?!"

Adeleine (struggling)* "Is this supposed to happen?!"

[Marx, instead of helping, steps back, observing with a mix of shock and amusement.*

Susie* "This is not part of the plan!"

[Marx spots Mard sneaking in with a cake. He gets an idea.*

Marx* "Mard! The cake!"

Mard* "Right!"

[Mard approaches the ensnared group cautiously and holds the cake up to Kirby, whose chains pause their thrashing.*

Mard (enticingly)* "Kirby! Look what I've got! Your favorite... A delicious cake!"

[Kirby's blank, glowing eyes fixate on the cake, a droplet of drool betraying his entrancement. As his focus shifts, the chains retract into his chest, releasing everyone.*

Galacta Knight (recovering)* "What... was that?"

Kirby (back to normal, cheerfully)* "Poyo! Cake!"

[Everyone exchanges bewildered looks, then glances at Marx.*

Cuphead* "I'm not sure what just happened, but I'm glad it's over."

Ms. Chalice* "Agreed. But next time, let's leave the rituals to the storybooks, yeah?"

[The tension breaks as Kirby starts happily devouring the cake, and everyone gradually joins in, laughing and sharing the cake.*

Magolor* "Well, at least every adventure with Kirby ends sweetly."

Tiff* "Yeah. Let's just stick to what we know best. Fighting the bad guys, not... whatever this was."

[The scene closes with the group united once again, their bonds strengthened by the bizarre ordeal, ready for whatever adventure or challenge comes next.*
