FLS, they look great, so tiny I too loved the film ghost ship, although couldn;t remember the names of the characters!!

As I'm sure TM will tell you they LOVE to chomp up cardboard - toilet roll inners, small food boxes etc etc. I would also suggest you remove the plastic bowl and replace it with a ceramic one (they will chew it sooner or later but cannot do so with a ceramic one).

I'm so glad your Dad remembered about Dodge, now they both have a happy future, together and aren't gerbs curled up together the sweetest thing
