Maybe the rest of us could shrink, then Raevis could stay normal size for now and be the only one to shrink after he befriends the owls.

J-H, if this adventure relies on us walking through the yard, and using the owls would mess up the adventure, it might be better to have the owls prevented from entering without getting zapped, instead of them having free passage. We wouldn't have even pursued this option if that had been the case.
