Tonkachi

Tonkachi (トンカチ ) is an enemy in Wario Land 4. It appears exclusively in the final battle against the Golden Diva, being the fourth of the five creatures that she produces in an attempt to harm Wario. Its name means "hammer", which is what it is. When Tonkachi is first thrown down by the Golden Diva, it has spikes along the sides, which will cause damage to Wario if they are to make contact. The spikes will disappear shortly after hitting the ground, and Wario can then pick it up and throw it upwards. If the hammer falls back on top of Wario's head, it will have the same effect as a Menhanmā, transforming him into Bouncy Wario. While he is bouncing like a spring, Wario can press to launch himself upward. If he hits the Diva's face, it will cause her damage and counter her attack.
