Baby Sheegoths initially lie buried in snow drifts, but they will awaken and attack once Samus comes near. They will spit balls of frozen gas at Samus, and will also try to ram attack her. Avoid these attacks by maintaining a healthy distance or attacking from above on platforms. Beam and Missile attacks will reflect off their strong frontal armor, but if Samus circles around behind them, she can attack their vulnerable backs. Once the back is destroyed, however, they can be attacked from any angle. Note they are also vulnerable to Wave Beam attacks.
