There is a special encounter in which a player can come across a whale's corpse in the middle of the desert, called "Crashed Whale." The description on the whale itself says "This whale appears to have fallen from a great height", and next to the whale's corpse is a box containing a flower pot of daisies.
This is a reference to the book The Hitchhiker's Guide to the Galaxy, in which a pair of nuclear missiles were transformed mid-air by an Infinite Improbability Drive, turning them into a sperm whale and a bowl of petunias.
