Activity level will vary with species, but of course, you want to avoid the runt that cowers in the corner, as well as the hyperactive one of the bunch.
Play dodgeball, a simple form of baseball, sliding Runt through obstacle courses; just little quick and easy games that will wile away some of your time.
Escape from the bullies, help Runt find food and Abby self-confidence, and save the world: and that's just in the morning.
Most of the time you'll play Chicken Little, but every so often you'll get to play Runt (the pig) or Abby (the mallard).
The smallest one of the litter was called the runt.
