At the end of the round, the current player rolls both of the Giant Wave dice and removes all of the tiles from the rows that match the number and color of the dice by discarding them face-up.

Giant Waves do not remove a tile with a Bird token on it. If a tile with a Bird token is about to be removed, remove the Bird token instead. However, if the tile with a Bird token is targeted by both Giant Wave dice (at the intersection of the rolls), both the Bird token and the tile are removed.
