Legendary mushroom cards are always Gift cards, making 2 total variations of cards (2 colors and 1 type).
Before the game starts, each of the 2 colors of legendary mushroom card is randomly assigned a mushroom card effect, out of a list of 2 possible effects. For the duration of the game, any given color of legendary mushroom card will consistently have the same effect that was randomly assigned to that color at the start of the game.
Although each legendary mushroom's effect is determined at the start of the game, these effects are initially hidden to the player. All legendary mushroom cards will initially have their effect description listed as "Smells notoriously funky." (if the card is Legendary Red Mushroom) or "Smells eerily funky." (if the card is Phantom Blue Mushroom), obfuscating their actual effect. When a legendary mushroom card is first obtained, the description of that color of legendary mushroom card will be changed to reveal its true effect, with all new legendary mushrooms of that same color now bearing the revised description. In Normal Mode, the description is only changed for the player who obtained it, while in Co-op Mode, the description is changed for all players.
