accessible version (not an exact replication, i'm more aiming for an equivalent user experience):
Kirby and Bandana Dee are giving Elfilin a tour of Castle Dedede.
Bandee, happy: ...And finally, my room!
Bandee opens the door. The three of them go in.
Bandee: Man, it's been so long since I've last been in here!
Bandee, happy: It's good to be home!
Elfilin, happy: It's a really nice room!
Elfilin: ...Um, what are all these big boxes for?
Bandee, eyes sparkling: Oh! My apple juice collection!
Bandee zips over to the large boxes, stabs one open with a spear, and pulls out a juice box, all in the span of a second or two.
Bandee happily sips apple juice.
Elfilin, shocked: Whoa...
Kirby, smiling: Bandee just loves apple juice! Dedede put all those boxes here just for him!
Bandee, happy: I haven't had any in so long! It's as good as ever!
Kirby, smiling wide: ...I want some too!
Bandee, happy: Here, catch!
Kirby, smiling: Thanks Bandee!
Kirby realizes something.
Kirby: Wait!
Kirby runs over to the apple juice boxes, his own unopened juice box in hand.
Kirby, smiling wide: Let's play the Apple Juice Game!
Elfilin, confused: The Apple Juice Game?
Bandee, happy: The Apple Juice Game!
Bandee: Whoever drinks the most apple juice wins!
Kirby, smiling wide: It's a thing we do a lot whenever I visit Bandee's room!
Kirby, smiling: Ready, Bandee?
Bandee finishes his juice box and grabs a new one.
Bandee: Ready! 3... 2... 1...
Kirby and Bandee, happily in unison: Go!
Kirby and Bandee drink apple juice at... well, at the pace you'd expect from those two in particular, really.
Bandee's simultaneously humming the Apple Scramble theme. Somehow.
Elfilin, scared: Don't drink so fast!
Kirby and Bandee, to the surprise of nobody but Elfilin, don't listen.
...In fact, they start to drink even faster.
Elfilin, worried: Aren't you guys afraid of choking?
No response. They're both too busy drinking apple juice.
They finish juice box after juice box after juice box. The empty, discarded juice boxes form an ever-growing pile on the floor.
As the game goes on, Elfilin has some inner monologue.
Shocked: That's more than ten juice boxes already!
Scared: How many more are they gonna drink?!
Back to normal: ...Huh, was Bandee humming something this whole time?
Happy: ...It's kinda catchy!
As the song reaches its climax, Kirby joins in on the humming.
In pain: Ow! My eardrums-- Whoa!
Shocked: How did that pile of empty juice boxes suddenly become twice as big!?
Elfilin's monologue ends.
Kirby and Bandee hum the final five notes of the song as they finish off the final few juice boxes in the large box.
Bandee, happy: ...And we're outta apple juice!
Kirby, happy: Poyo!
Elfilin, worried: ...Um, how many juice boxes was that...?
Bandee, happy: Well, each of these big boxes has 30 juice boxes, so that's how many we drank in total!
Elfilin is shocked into silence.
Elfilin, putting up a happy face: ...So, then... who won?
Bandee, happy: Oh, we don't actually keep track!
Kirby, happy: We both got to drink a whole bunch of yummy apple juice!
Bandee, happy: So in a way, we both won!
Elfilin: ...Oh...
Bandee: Wanna try some for yourself, Elfilin?
Elfilin: ...Um, sure...
Elfilin: But, um, just one, please.
Bandee opens up another large box. He takes out five juice boxes: two for him, two for Kirby, and one for Elfilin.
Elfilin, happy: ...Wow! It is really tasty!
Bandee, happy: I'm glad you like it!
Kirby, smiling wide: Maybe you could join us next time we play the Apple Juice Game?
Elfilin thinks for a moment.
Elfilin, happy: ...Well, it does seem kinda fun!
The end.
