Sentrobe

Sentrobes are enemies in SS undefined.

Characteristics
Sentrobes are round, flying robots found mainly in the Lanayru Mining Facility, only becoming active when under the effects of a Timeshift Stone. They have eyes in the center of their bodies and they fly around using a propeller attached to its inner body. They are separated vertically by their metallic shell, which opens to shoot missiles at Link. These missiles can be reflected with a Shield Attack or sword strike to damage the Sentrobe. They can only withstand being struck by their missiles twice before they blow up, jettisoning Rupees in all directions.

Sentrobe Bomb
After one of the Sentrobe's missiles is deflected back at them, they will launch Sentrobe Bombs, which are smaller, more easily destructible versions of the Sentrobes. When deployed, Sentrobe Bombs follow Link around and blow up after a set time limit. Link can safely destroy them by slicing them alongside their opening, either vertically or horizontally. Unlike their larger counterparts, they cannot fire missiles at Link. When Sentrobe Bombs are following Link, they are accompanied by a high-pitch, mechanical theme.
