Notes and trivia

• As its idle animation, it will occasionally snap forward, as if attacking.
• Unlike other companions, the zergling appears on [Track Beasts].
• Will attack nearby Grunty The Murloc Marine.
• Zergling, from the original Collector's Edition, is based off the Zergling unit from StarCraft. The Zergling is weak, but can easily swarm the enemy in larger numbers for a quick victory. The battle pet has the themed abilities [Metabolic Boost] and [Zergling Rush].
