Lucky Droid

Lucky Droids are very rare Droids that can spawn in any world, including RXJyb3I=.

Appearance
The Lucky Droid has a yellow torso, white limbs and white head. It has a white droid helmet with cat ears and a yellow circuit symbol on the front. The droid uses the ":3" face. It has a long white tail at the back.

Its torso has a timer that counts down from 10, causing it to disappear if said timer runs out.

Behavior
Lucky Droids can spawn in any room except for special rooms [please confirm]. However, they are very rare to encounter.

Lucky Droids spawn in the middle of the room. They do not move or damage anyone, similar to a Friendly Droid. Additionally, when a Lucky Droid spawns, it makes a special sound effect. After 10 seconds, the droid dies on its own and disappears without giving any circuits.

If killed in time, the Droid will drop Circuits equivalent to the room number.

Since killing this enemy is not required to move to the next room, it is unaffected by abilities or items that affect enemies.
