Minecraft Dungeons:Key Golem

The Key Golem is a small mob in Minecraft Dungeons which helps the player unlock certain doors upon collection.

Behavior
The Key Golem will start out asleep. When it is awake, it will attempt to evade the player at any point it can. The player has to hit it to collect it, at which point it gets strapped to their back. The Key Golem will squirm and yell while on the player's back. If the player is damaged while the key golem is on their back, the key golem gets off and resumes running away. If the player manages to get to a locked door while the Key Golem is still with them, it will disappear, the lock will turn yellow, and then the door will open. There is another key golem that is coloured blue and is used to open blue doors. Players need to beware of the fact that the golden key can be picked up by a some mobs. If the mob gets killed the key has a certain possibility to vanish together, which makes the whole stage unplayable.
