Skullrope

Skullropes are reccuring enemies in the Zelda series. They are weak snake-like enemies with a skull for a head that serves as common threats in the games they appear in. They debuted in The Legend of Zelda: A Link to the Past.

The Legend of Zelda: A Link to the Past
In The Legend of Zelda: A Link to the Past, they are very weak enemies from the Dark World that usually attack in groups. They simply attack by trying to ram into Link. They appear for the first time in the Thieves' Town and can be considered the Dark World equivalent of the Ropes.

The Legend of Zelda: A Link between Worlds
In The Legend of Zelda: A Link Between Worlds, they are very similar to their A Link to the Past incarnation. They are also weak enemies that are now even more common than before as they also appear in regular Hyrule and most dungeons while also serving as the Lorulean counterpart of the Ropes. They still ram into Link and will often be encountered in groups.

The Legend of Zelda: Tri Force Heroes
In The Legend of Zelda: Tri Force Heroes, the Skullrope is once again similar to both of its past appearances. It will try to ram into Link as its only attack. The Skullrope appears in The Ruins and in The Dunes.
