Broken Age? I once planned to start a fanfic with Katie (a lavender female puffball) as Vella, and Kirby as Shay, but it kinda got lost...
I'll make it happen as an RP on the Basement.
Some changes are:
(Velafeast)
Katie sets up a dummy to fool Mog Chothra, instead of just plain escaping like Vella did.
Katie has no clue what of God's Green Earth a Maidens' Feast is about until the day arrives.
The Contestants for the Sugar Bunting Maidens' Feast have the frosting writings as follows: "Now with More Protein", "Contains Alcohol", "Eat Your Veggies", "Caution: Contents are HOT!", and "Just Plain Yum".
The characters in Meriloft have some RIDICULOUS names: H'r'c', ' (at first mistaken for Justin Apostrophe), J'nna, M'kay, O'Bri'n, F'ed, N'rcis'us, J'e, H'r'ld, G'rge, Brend'n, and G''.
There will be a random guy who shouts "HEYOOOOOOOOO!!" at the worst possible opportunities.
(Shayspace)
Kirby will have his evil twin brother Keeby "guide" him through the vast expanses of space, as opposed to Shay having his aggressively overprotective mother.
Kirby's cockpit will be more adult-themed than Shay's pre-school cockpit.
The missions will be in order: S.S. Enterprise under attack by the Klingons, an army of robot Waddle Dees, a mechanical replica of Fire Lion, and two robot Phan-Phans on a train.
Kirby's playtime will put him in a fierce gladiator-type competition, where he's forced to fight with only a laser knife, as opposed to Shay's diabetic playtime adventures where he's partnered up with a bunch of stuffies.
Kirby will befriend a mysterious orange puffball with blue blush marks and feet named Mab Hidan instead of that wolf named Marek befriended by Shay.
The ship will have an intense steampunk theme through the inner workings.
The ship will have a mysterious core, along the likes of an Energy Sphere.
The galaxy will still be called Prima Doom, but it will have 0 from Kirby's Dream Land 3 as the central antagonist.
