Chasupa

The Eye Keese (Chasupa) are mutated forms of Keese that dwell in the Dark World. They can easily be killed by a single strike of the sword. They are found in A Link to the Past in either Hyrule Castle tower or the Dark World. Aghanim must have thought of these to deter timid intruders. They have the same amount of health as a normal Keese.
