Tub-sub

Tub-subs are barrel-like submarine enemies from Wario Land: Shake It!. They appear in underwater levels, such as Wavy Waters. They attempt to attack Wario in his Subwarine by using missiles of their own. Tub-subs take three missile hits to defeat, and drop three small gold coins once destroyed. There are two colorations of Tub-subs, one with brown wood and gray metal, and one with gray wood and purple metal. Brown ones move vertically to try and attack Wario after taking damage once, while gray ones do not. Tub-subs cannot move diagonally or turn, and only fire missiles in a horizontal line.
