Once you have all three magic beans (from the Pig, Longlocks, and the Bad Wolf), Syanna suggests planting them by the path near the tower. When you reach the planting field, you’re set upon by a dozen appearing Pixies. Remove these annoyances, then inspect the investigation area (using your Witcher Senses) to find the correct spot.
You place the three beans, before Syanna quickly retreats to cover. A moment later, the ground erupts as a mass of snaking tendrils bursts upward, knocking you off your feet.
You climb the towering beanstalk with Syanna, ascending into, and then onto the clouds above the Fablesphere. As you look over to Syanna, she tells you there will be time to admire the view later. First though, is the owner of this castle. A lumbering giant crashes out from the entrance, intent on grinding your bones to make his bread.
