The Crawling Skull is a recurring enemy in the Rosenkreuzstilette series.
The Crawling Skull is a near-invulnerable enemy that crawls back and forth on the ground, speeding up when the player is on the same level as them. In Rosenkreuzstilette, they can only be destroyed by powerful special weapons such as the Grollschwert, Liebessturm, Lilli and Strudel. Crawling Skulls function similarly to the Spines from the Mega Man series.
In Rosenkreuzstilette, Crawling Skulls are found in the Snowfield (Freudia's stage), the Luftfeste Sleipnir (Luste's stage), the Ghost Town (Grolla's stage), the Research Tower (Liebea's stage), and the second and third stages of Zeppelin's Castle.
In Freudenstachel, they are found in the Castle Grounds (the opening stage), the Luftfeste Sleipnir, the Mountainside Dungeon (Grolla's stage), the Zuverburg Clock Tower (Sichte's stage), the White Desert (Liebea's stage), the Zeppy Ruins (Schwer's stage), and the first stage of Iris Palace II.
