Here he is in action as Firefly: And Man-Bat:
McKinley gets to take part as well, but doesn't really get in on the action (although, now that she has seen her brother jump of every piece of furniture we own, she has attempted to follow). Yes, she sat still for a few days after her cast was put on, but then she started an army crawl and now she is full-on RUNNING in her cast. More than that, she is actually climbing onto my bed and throwing herself onto the mattress with gusto. Talk about thrill-seeking.
