  Discrete dynamical models of walking droplets ("walkers") have allowed swift
numerical experiments revealing heretofore unobserved quantum statistics and
related behaviors in a classical hydrodynamic system. We present evidence that
one such model of walking droplets exhibits the empirically elusive $n$-bounce
resonances that are traditionally seen in the scattering of solitary waves
governed by covariant nonlinear field theories with polynomial
self-interaction. A numerical investigation of the chosen model of interacting
walking droplets reveals a fractal structure of resonances in the velocity
in--velocity out diagram, much like the usual maps constructed for collisions
of solitary waves. We suggest avenues for further theoretical analysis of
walker collisions, which may connect this discrete model to the field-theoretic
setting, as well as directions towards new experimental realizations $n$-bounce
resonances.
