I was wondering, are you planning to use Teen Tiny in Gale Gare? Well, if it happens before DK64 then you should use Kid Tiny for consistency's sake.
So a while back, you mentioned a fifth Kong being a possibility. There was talk of a new kong named Doug Kong, and of Funky Kong, and more recently, Tiny Kong.
Why not follow DKC'S trend of adding a new Kong every installment? DKC added Diddy, DKC2 introduced Dixie, DKC3 brought Kiddy into the group, and your DKC5 is Tiny's debut.
How about a whole new, never-before-seen Kong, like Doug Kong, but a new female like you said named Sassy Kong? In the attachment below, I give you a Title Screen featuring our new Monkey pal. I include a Game Over screen from a few pages back featuring Sassy scratched up, her bandana with a bite taken out of it, a swollen eye, and some tears. I even made a render of her playing her instrument, the Piccolo, for the soundtrack pics. And in case you want to make a new title or a promo pic, I included Sassy's title screen pose without the BG or the other Kongs. All this in PSDs! But that's not all. I have a Brawl-style Sassy in the form of a DAE model, as well as a Texture BRRES for you to open in BrawlBox.
She would be a Light Kong, and her skill? Throwing Heavy Kongs as if they were Light Kongs and swimming almost as fast as Winky. You see, Sassy Kong is a friend of Dixie's who is incredibly strong for her size and age. She has the speed and size of Diddy and Dixie, with the power of DK or Kiddy. As such, she has no skill like the water skip, hair spin, kong ride or hand slam. Her skill is super strength.
Right now I'm working on her sprites for the actual game, but that's the hard part so don't expect those for a while. I've barely got a single sprite of her done
Now I was thinking, for Sassy's Hideout, it could be a world kinda like Pacifica in DKC3 GBA. Connected to the other worlds, but placed in an out of the way area. Her world's gimmick, like the hot air balloons and crocodiles from DKC2's lava world, would be power barrels. Jumping into a Power Barrel with a specific symbol on it grants a unique power.
A Blaze Barrel that is red and on fire on it spins around like a LaunchBarrel, but instead of shooting a Kong, it shoots a lava ball like those cannons in Mekanos then drops the Kong out.
A Ghost Barrel that is purple and semitransparent shoots the Kongs through walls they can't normally get through WITHOUT breaking the wall.
A Nature Barrel that is green and has vines wrapped around it reveals a temporary vine that disappears, like a Ghost Rope from DKC2's Gloomy Gulch.
An Aqua Barrel that is blue and watery turns the Kong's into water, giving them a blue palette, for a short time, letting them go through enemies until a timer runs out.
An Electro Barrel that is yellow and has electricity around it lights up a normally dark room for a short time.
An Ice Barrel that is cyan and has icicles hanging from it spews out an ice statue of DK that can confuse the floating hand boss and cause him to grab the statue instead of a Kong, leaving his weak spot, the wrist, open for attacking.
A Graveyard archetype level called Spooky Coaster Sprint, with fake Mr. X's and Kackles floating around and some Zingers. These two enemies don't do anything, but the Zingers do. It has Ghost Barrels to keep from crashing into semitransparent walls.
A stage called Essence Blaze Elevator, which uses a (preferably custom) Factory/Lava tileset and has an elevator with Blaze Barrels scattered around to combat enemies on the way up.
A level called Vineswing Volley using a Jungle Jinx, Tree Top Town and Gusty Glade fusion that is very tropical. In it, you jump into Nature Barrels to place vines to swing across pits.
A level called Coral Fusion Caverns, using Fish Food Frenzy's tileset mixed with Glimmering Galleon and Coral Capters, with Aqua Barrels to allow merging into the water for short bursts to pass an obstacle that Kongs cannot pass on their own.
A level called Blackout Bloom using a custom Winky's Walkway mixed with Squawk's Shaft and Murky Mill. It has with blackouts where your Electro Barrel powers allow you to see until the barrel wears off.
A level called Elemental Environment that starts as DKC4 Desert, shifts to the Millstone Madness tileset, goes to Hot Head Hop tileset, and finally Fire-Ball Frenzy, where every skill must be used wisely to survive.
A Snow Level called Frosty Klaw Khaos using DKC4's unique snow tileset where you must use the Ice Barrel to make an Ice Statue to confuse the boss.
I can provide sprites for Sassy if you like her, her animal buddy the Gnice [a friendly Gnawty, because naughty and nice], the Frosty Klaw, and the Power Barrels, and I would assume that Phyreburnz could take care of the level designs, but I can help with those too if needed.
EDIT: Frosty Klaw completed!
In his battle, he starts in the BG, flies around a bit, then punches the mountain. Snow-boulders fall down, but evade them all, and an Ice Barrel is your reward. Use it quickly and get away, because Frosty Klaw will fly into the foreground and grab the statue when possible, or a Kong if there is no statue or if you lost the barrel. While grabbing either, he will shake them violently before jumping back again. Hit him on the wrist while he squeezes the Ice DK, and he'll fly back and repeat, but faster. Hit him twice more and he falls!
EDIT2: Power Barrels Completed!
I've already explained these...
EDIT3: Gnice completed!
This Gnawty isn't so naughty! Why, Gnice is nice! He his walk is a hop like Very Gnawty, he jumps about as high as Diddy, and can slide on his belly like a penguin. Kinda like the penguin suit from Mario, if you've played NSMBU or NSMBWii. When he's hurt, her screeches and hops off at a high speed. While waiting, he chitters towards the screen.
so for Sassy and her levels, if you like her and want me to finish working on her, all that's left is Sassy's sprites, Gnice's crate, barrel, sign and token, her hideout to be modeled (I can't do this), her actual levels (It would take me forever to do this >.< but I could if really needed), and the programming for her.
Out of curiousity, what sprites would she need? Life, team-ups, her front-flip (which is her roll/cartwheel/spin) and all, but is there a list that I can use to be sure I do everything?
Anyway, expect my sprites for her to be done in september or october. It takes a while to get that DKC look.
If anyone wants to help: She looks like this

Obviously I need someone else to do her hideout model, I really want to see Sassy in this project but I simply cannot model like that. Same for her levels and programming.
between Donkey Kong Country 3 and Donkey Kong 64, maybe there is something to do with this in the story of Donkey Kong Country 4 Kong return. What do you think about that?
(maybe a heroic death because he doesn't even appear after in Donkey Kong 64). It can be a good idea to explain why Cranky Kong has stop to complain about Donkey Kong 
and finally help him in his quest( there too it could have a link with the Wrinkly's death). And finally, maybe not as real character but just explain why 3 news Kongs ( Tiny, Lanky ,and Chunky) have joined the party.
