Splash Mine

The Splash Mine (スプラッシュマイン) is the first Special Weapon that Mega Man Volnutt obtains in Mega Man Legends. It is made from the Mine Parts Kit given by the Junk Shop owner. Mega Man plants mines on the ground with this special weapon. The mines explode over time or when the mines are stepped on or run over. The Splash Mine can be very useful when fighting the Blumebears, and with proper timing can vanquish them and retrieve the Bonne Key before they can even move.
