DK breaks free of his ropes, then gives Kaptain K. Rool a HUGE uppercut, throwing him smashing through the window of the Flying Krock and sending him plummeting down Crocodile Isle and into the sea. At which point he is attacked by sharks (and survives for the true final battle in the center of Crocodile Isle).
Complete Snow Barrel Blast's final Barrel Cannon segment in DKC 1 with no mistakes and a 3-up balloon will be waiting for you.
Finding the nested bonus room in Oil Drum Alley and completing all three sections of it for a total of six extra lives.
Get 102% in Diddy's Kong Quest and you get the pleasure of watching Crocodile Isle explode and sink in what may be the Super Nintendo's most beautifully rendered cutscene ever.
Freeing the Queen Banana Bird in DKC 3 will have her drop an enormous egg on K. Rool.
Normally, getting full completion in DKC 3 amounts to 103%. Then there's doing it with the TUFST code applied to a new game: You remove all but four DK barrels throughout the game making you a One-Hit-Point Wonder for the majority of it, remove checkpoints even for the longest of levels, and you get rewarded with 105%, the Immortal Monkey title, and a trophy of Cranky Kong.
The sequels clever Take That! to their competitors of the day, including a pair of vividly colored shoes and a ray gun being lumped near a trash can with a nearby sign saying "No Hopers". And since this was around the time Sega was about to go into a steep decline, the timing of this gag couldn't have been more on the mark.
Speaking of rival companies, the original games commercial and Nintendo Power promo VHS giving Sega a verbal smack down is an unforgettable meta moment of awesome; after years of Sega keeping Nintendo on the ropes, be it with their cutting edge Sega Genesis library and their infamous in-your-face ad campaigns, when Sega brought themselves down with their failing CD and 32X add ons, Nintendo took advantage of a once-in-a-lifetime oppurtunity and proceeded to give their rival a well earned taste of their own medicine by championing this games groundbreaking cgi, pointing out that not only did it NOT need a superfluous add on for its cutting edge graphics, it was also only available on their "inferior" rival console! And to hammer it home, Sega, normally known for being one step ahead of Nintendo in being cutting edge, ended up being forced toape Nintendo's beloved game with the Sonic 3D Blast, Sonic Blast and Vectorman games, which, despite being well liked to ok hits, never saw a speck of DKC's success, except in the UK, where even this couldn't help the SNES compete against the Mega Drive.
Also of note is the sub series Donkey Kong Land (and the GBC port of the first game) which not only proved that the little gray brick could handle the jaw dropping cgi of the original game in 8 bit form, but silenced critics who said the original game was only liked because of its fancy graphics, bringing all the fun of the console game on the go!
The end of the intro screen in the first game gives Cranky one. Let's just say it involves TNT in close proximity to his grandson.
In "Double Date Trouble", When a rainstorm rusts the Trigger Barrels that activate the traps on the footbridge to Cranky's Cabin, DK goes to Bluster's Barrelworks to get new ones, but the factory is closed for the weekend. DK tries to use the machinery to make his own, and suceeds, but ends up trapped in another barrel. Bluster comes by, sees DK's plight, and decides to leave him there as a mean-spirited lesson for monkeying about with the factory. DK convinces him to send the Trigger Barrels to Cranky's with some smooth talk, proving that even a dumb ape can be Guile Hero if he knows who he's talking to;
Donkey: Okay, Bluster, leave me 'till Monday. But I don't know who's going to pay for all these barrels.
Bluster:Pay? What do you mean, Someone's got to pay!
Donkey: Well, Cranky ordered them, but he said he wasn't paying a dime, unless he got same-day delivery!
