I had hoped Runt of the Litter [$ 3.99] would put a new spin on the theme, with its central conceit being that you need to raise and train a war gryphon.
What this means is that runtsof two littersof beagles will be bred together in hopes that their litter will be much smaller; then this process will be repeated with the new litter and so on and so on, until a litter with «teacup» beagles exists.
