Warp Whistle Whirlwind
When you find one of the secret Warp Whistles, use it on the map screen and it will play a tune and summon a whirlwind to take you to Warp Zone.
Both the tune and the act of summoning a whirlwind with the flute are taken from The Legend of Zelda (NES).

Mario Bros.
When playing the 2-Player game, each player can challenge the other player by selecting their M or L icon on the map screen. The minigame is based on the Mario Bros. arcade game.
Players can race to 5 Coins to play the next round, and steal each others' Goal Cards.

N Card
In Toad's card-matching minigame, the cards feature an Ace of Spades with "N" on the back. These cards are based on actual playing cards manufactured by Nintendo when they were predominantly a playing card manufacturer.
