The pigs often notice when we go outside or just smell basil wafting on the air, and will demand a treat from us. But because Grizzly tends to be out and about more than Bean, who loves to nap, sometimes he smells it first. So he'll start wheeking and begging for treats.
If he wheeks wake Bean up, though, Bean doesn't hesitate to join the begging, even if he's not sure what just happened.
