We solve exactly a special case of the anisotropic directed-bond percolation problem in three dimensions, in which the occupation probability is 1 along two spatial directions, by mapping it to a five-vertex model. We determine the asymptotic shape of the infinite cluster and hence the direction dependent critical probability. The exponents characterizing the fluctuations of the boundary of the wetted cluster in d dimensions are related to those of the (d\ensuremath-2)-dimensional KPZ equation.
