==Secret==
<section begin="qiskullcavern" />After reading [[Secret Notesひみつのメモ#Secret Note ひみつのメモ #10|Secret Note ひみつのメモ #10]], the player will find [[Mr. QiミスターQi]] at level 100 of the [[Skull Cavernドクロの洞窟]]. A cutscene ensues in which:{{collapse|content=Mr. Qi ミスターQi will either congratulate the player for reaching level 100 without using [[Staircase階段]]s or say the player is "clever" but not "honorable" for using them. In either case, he will award the player with Iridium Snake Milk, which permanently increases the player's [[Health体力]] by 25 points.}}
