Unknown[Metroid Prime]

Metroid Prime

When it isn't hunting, a Splinter will secret a protective cocoon around itself and enter a state of hibernation. Localized seismic disturbances will awaken the Splinter, triggering a state of blood frenzy in the process. While in this state, a Splinter emits pheromones that trigger frenzy in all nearby Splinters. Disturbing a pack of Splinters is not advisable.
