Trivia

 * If the player plays Seeing Stars and does not try to fill the area with Starfruit, he or she can somewhat simulate this mode. This can be done without cheating.
 * This is arguably the most difficult Survival: Endless mode, as all difficult zombies appear, but there is no pool for protection. In addition, mushrooms need to be awakened by Coffee Bean.
