If Stormbeard moves into a space that contains a Hero Stone or the Shimmering Widget, he may instantly pick up the item. If more than one item is stacked there, Stormbeard may instantly pick up all items in the hex. When an item is taken, its token is removed from the board and placed on the table near the hero player.
Yup... saw that.
And I take it to mean even if Stormbeard moves through and doesn't stop.
Just asking to be sure...
