As in a few episodes before (Entei at Your Own Risk - 15'02") , where a Misdreavus was captured in a net by Team Rocket, now a Misdreavus is trapped by a fallen tree. We've seen Gengar to move through solid objects multiple times in the past. So, a Ghost Pokemon doesn't have this ability just because it is a Ghost Pokemon.Lunasol (talk) 18:19, 31 October 2013 (UTC)
