In box 1, Barney and Fluffy are still around but with even less to show.
Barney goes into the box.
Barney is sitting on the hole doing a bit of "white cheek flashing" to attract his mate.
Fluffy responds, following Barney inside 5 seconds later.
Here is an inside view of Fluffy entering the box.
Barney leaves, of course, at full speed!
