Drivels are flying creatures that live in Phase 7. Their behavior consists of moving back and forth in the air. When Samus approaches, they spit liquid acid. If this drop hits the ground, it will burst and ricochet. The drop makes an explosion sound. The drop can be shot to produce an Energy Capsule.
Metroid II manualEdit
"They move back and forth in the air. When Samus approaches, they will spit a strong liquid acid."
- It is unknown if the Drivel species was infected by the X Parasites, as Samus never encountered any Drivel-X in Fusion.
