Replaced by Frogs?

It's true.  Thora has chickened out and has had to be replaced by frogs.  Not a suitable substitute in my opinion, but the frogs are excited.  In Thora's defense, she does have a lot on her plate these days; I mean, being sulky and difficult requires a great deal of energy and she certainly excels at both.  I just hope she doesn't change her mind later on; I'd hate to see the frogs disappointed.  They've already got their little bags packed.
