Tempting, aren't they?
But I wouldn't dare.
These berries strike me as just the thing a wicked witch would use to lure Hansel and Gretel down the path and deeper into the woods. "Oooh," the witch would say, "delicious, aren't they? So sweet and jooooseeee." And poor Gretel would stuff her cheeks. She wouldn't know they were poison berries. By the time she was dizzy and sick to her stomach it would be too late, she'd be in the witch's cabin, hidden away on a hillock in the Arroyo Seco—I mean the woods—where most people don't even know there's a cabin at all.
Hansel had better enlist all his handsome prince friends to help him find her, or he's going to have to walk the dog by himself from now on.
