Turtle Rock (Boss)

Turtle Rock is a mini-boss in, and its Game Boy Color remake,. At first it is actually a part of the Turtle Rock dungeon, where it is seemingly made of stone and is blocking the entrance to the dungeon, akin to the entrance of the eponymous dungeon in. However, by playing the Frog's Song of Soul, the stone will break and the head will come to life and will try to attack Link by extending its neck to slam into him, similar to the behavior of Trinexx in A Link to the Past. Unlike Trinexx, Turtle Rock can be harmed by simply attacking with a sword, and is relatively weak. Once Turtle Rock is destroyed, the entrance to the dungeon is revealed.
