Barnaclejack

The Barnaclejack, also known as High Stepper, Springball or Springstepper, is a recurring creature in the Mana series.

Characteristics
Introduced as an enemy in Final Fantasy Adventure, these diminutive Mushboom-like creatures have coiled springs in their bodies. As an enemy, this elasticity allows the barnaclejack to attack with its head and "neck". They also move about by bouncing around randomly, wobbling as they go. More often than not, however, these living springs are helpful critters, launching into the air adventurers who jump on their heads.
