  We investigate the collision of a new class of topological defects that tends
to become compact as a control parameter increases to larger and larger values
These new compactlike defects have, in general, more than one internal discrete
mode depending on the value of the control parameter and, as usual, there is a
critical velocity above which the defects escape after the collision. We
noticed that below the critical velocity there are the windows of escape
presenting fractal structure. An interesting novelty is the appearance of
metastable structures with the formation of compactlike defects, maintaining a
fixed distance from each other. Another new feature is the formation of boosted
localized distributions of the scalar field which we called moving oscillons.
These oscillons carry away almost all scalar field energy producing a complete
disruption of the compactlike defects. The pattern of the moving oscillons
depends on the control parameter, and becomes more complex as we increase its
value. We conjecture that the new effects may be connected with the presence of
more than one vibrational mode in the spectrum of the stability potential of
the model under investigation.
