I figured I'd hang a lampshade on the switch to CGI Lego by having the characters comment on how this allowed things that wouldn't normally be possible due to the particular anatomy of Lego figures, like their lack of ears.
Then I remembered that the head I'd been using for the pirate captain already had an earring drawn on, so I guess this comic really isn't that funny any more.
Though I think the real earring looks a bit fake compared to the CGI one I was planning on using.
