Creature — Fungus Lizard 2/2, 3G (4)
Rare
Whenever Fungusaur is dealt damage, put a +1/+1 counter on it.
Rather than sheltering her young, the female fungusaur often injures her own offspring, thereby ensuring their rapid growth.
Illus. Scott M. Fischer

10/4/2004: If more than one creature damages it at one time, it only gets one counter.
