Dueling Games: Everyone knows about the Mario-Sonic rivalry as the main front of the Nintendo-Sega Console Wars, but it was this game dueling with Sonic the Hedgehog that was the focus.
Raocow has called Charging Chuck and Yoshi "Football Charlie" and "Stupid Horse", respectively.
GameFAQs' LUE board uses the very box image of the game as its god. They also call it LUEshi, instead of Yoshi. They even have their own mod, if you're wondering.
