In 2018, Donkey Kong Country designer Gregg Mayles posted a tweet off the heels of King K. Rool's reveal as a playable character in Super Smash Bros. Ultimate featuring a naming sheet from the former game's development dated to March 8, 1994. This document contains several proposed names for various characters and the game itself, with Monkey Mayhem being listed as a working title. Other differences include the following:

• The names "Blonde Kong" and "Honey Kong" were suggested as alternate names for Candy Kong.
• King K. Rool was originally named "Kommander K. Rool".
• Rock Krock was originally named "Krocrock".
• Slippa was originally going to be called "Mr. Hister". This particular name appeared to be changed late in development, as an unused hint from Cranky Kong mentions Mr. Hister.
• Squidge was originally named "Mr. Squidge".
• Clambo was originally named "Ms. Clamity".
• Cranky Kong and Funky Kong's names were originally spelled "Crankey Kong" and "Funkey Kong".

Additionally, the naming sheet lists several proposed characters absent from the final game:

• An owl Animal Buddy named Hooter. In the replies to his tweet, Mayles stated that Hooter "was going to light the way with its night vision", and that it was eventually replaced by Squawks the parrot.
• A mole Animal Buddy named Miney, likely playing off of the counting rhyme "Eeny, meeny, miny, moe".
• A "Kremling Magician" named Kloak, who would later appear in Donkey Kong Country 2: Diddy's Kong Quest.
• A "Statue Kremling" named Krumble.
• A "Green Kremling" named Klanger.
• A "Robot Kremling" named Krocbot.
• A Moray eel enemy named Mobo.
• A fireball enemy named Fizzle.
• A yeti/"Iceman" enemy named Frozone. In the replies to his tweet, Mayles expressed amusement at "Frozone" also being the name of a character from the 2004 American animated film The Incredibles, stating that "We never used or copyrighted the name, so anyone could have used it." Indeed, "Frozone" is one of several entries on the naming sheet that doesn't have a trademark symbol attached to it. Coincidentally, the Donkey Kong Country television series would feature a yeti character of its own, Eddie the Mean Old Yeti.
• Two fish enemies named Bloop and Gloop; the latter would later appear as an enemy in Donkey Kong Land.
• A "nasty beetle" enemy named Veedub, who would later appear in Donkey Kong Country 2: Diddy's Kong Quest under the name Click-Clack.
