When Marty accidentally "steals" a pair of slippers from a department store, he plans an elaborate "heist" to return them and learns in the end that it's easier to own up to your mistakes than to cover them up.

When a litter of hedgehogs are temporarily relocated to the habitat, Alex, Marty, Melman, and Gloria become their "babysitters."
