Cranky's Cabin
Cranky Kong's cabin has a number of references to Rare's fighting game, Killer Instinct. There is a Killer Instinct arcade machine and a poster of Thunder, one of the fighters in the game.
On the map screen for Krazy Kremland, Cranky's Cabin appears as a fairground tent. There is a sign above it that reads "KI Here" and another Killer Instinct arcade machine outside.

Cranky's Video Game Heroes
When you complete the game, the number of DK Coins you have collected determines your position on the pedestal of "Cranky's Video Game Heroes". Unless you have collected enough DK Coins, first place is Mario, second place is Yoshi, and third place is Link (from The Legend of Zelda).
There is also a trash can signposted "No Hopers", which has Sonic the Hedgehog's shoes, and Earthworm Jim's gun next to it.

Minus World
In the instruction manual, the entry for the Plus and Minus Barrels reads:
"The Plus Barrels will add time to the timer, the Minus Barrel will send you into the Minus World! (Uhhh... wrong game. Actually they will take seconds away from the timer.)"
This refers to the Minus World, an infamous glitch in Super Mario Bros.
