Easter Eggs from the Star Fox series has been found in a few games in different series created by Nintendo. They most likely occur in Mario games. They rarely occur in any other Nintendo games, like F-Zero and Animal Crossing.
In Super Mario RPG: Legend of the Seven Stars, the Arwing appears as a small figurine in the Shop Hall within the Barrel Volcano while Mario is on the quest to find the sixth Star that was nearly taken away by the Axem Rangers for good. In Mario Golf, some common names, like Peppy Hare, appear in the tournament results hole after hole in certain Golf courses. In Mario & Luigi: Superstar Saga, one of the items that was supposed to be given from Fox McCloud is actually given to the Mario Bros by Professor E. Gadd for allowing him to sample one of the Coffee items created with sufficient amount of beans found in the Beanbean Kingdom.
In F-Zero games exluding the SNES games and Maximum Velocity, James McCloud that was Fox McCloud’s father also appeared to be in human form racing in F-Zero Grand Prix with the Little Wyvern as a modified machine from the Arwing. These Easter Eggs were actually developed to honor that actually James McCloud in the F-Zero series.
In Animal Crossing series excluding New Horizons, the Arwing appears in the Nintendo Set. However, the player who controls their avatar village must obtain it under certain circumstances in corresponding game titles. In Animal Crossing: New Leaf, you can obtain the Arwing if you give the Nookling Twins a fortune number that makes them give you such an Easter Egg.
