A stealthy model of Henger that is the second most common type in the games, tied with Sky Henger (the first being the original Henger). It appears in four installations before its name is finally changed, and its Plant sub-type is eventually revealed. It's always covered in camouflage (much like Tank or Gaboo Soldier) until it appears as a non-playable enemy in Monster Farm Online, in which is it simply green and is a soil elemental, weakened by thunder.
Etymology
An ambush is a surprise attack, usually accomplished by sneaking up on and surrounding the target.
Its later name is a play on the words herb (any plant with leaves, seeds, or flowers used for flavoring, food, medicine, or perfume) and Henger.
