+	The function bd.fake_beaver animates a beaver when another one has jumped
+	into the dam. This animation is performed into a cutscene block (between
+	START/END_CUT_SCENE()), so if the user opens the inventory a bit before
+	this function is called, the interface will froze, since in

+	are called (in bd.throw_bone_in_tar) and wait until it's closed,
+	then performs the animation.
