Katarina isn't the only one whose been looking for the beavers, as it
turns out. A number of her cousins have been beaver hunting too, and
they've found a lot of beavers including:
A whole shadow full of Shinto Televangelist beavers.
Some hyperintelligent, microscopic beavers busy building particle beam
weapons out of mud.
A Mile high city eating beavers named Reksark.
...but alas, none of them were her beavers. Poor Katarina.
