Slime Eye

Link encounters the Slime Eye (デグゾル, Degu Zol) in the Key Cavern dungeon in Link's Awakening. Link must use his Pegasus Boots to start the battle by ramming the back wall at full speed. Once Slime Eye appears, using the Pegasus Boots in combination with his Sword, Link must perform a Dash Attack and split the gigantic eye into two, and then slash the individual eyes to death. This gets Link the Sea Lily's Bell. This boss slightly resembles Vitreous and Wart.
