  The aloof baby Skyrme model is a (2+1)-dimensional theory with solitons that
are lightly bound. It is a low-dimensional analogue of a similar Skyrme model
in (3+1)-dimensions, where the lightly bound solitons have binding energies
comparable to nuclei. A previous study of static solitons in the aloof baby
Skyrme model revealed that multi-soliton bound states have a cluster structure,
with constituents that preserve their individual identities due to the
short-range repulsion and long-range attraction between solitons. Furthermore,
there are many different local energy minima that are all well-described by a
simple binary species particle model. In this paper we present the first
results on soliton dynamics in the aloof baby Skyrme model. Numerical field
theory simulations reveal that the lightly bound cluster structure results in a
variety of exotic soliton scattering events that are novel in comparison to
standard Skyrmion scattering. A dynamical version of the binary species point
particle model is shown to provide a good qualitative description of the
dynamics.
