Bloopers are recurring Mario enemies that have appeared in most of the games in the series, although they had their most unique appearance in Super Mario Sunshine. It was also the first game where Bloopers were able to stand on dry land.
Tips: Build from the head down, starting with the two big side pieces. Build down to the tentacles, then build the biggest two first and attach them to the body. Fully complete the other four tentacles, then also attach them to the body. Seal with the large octagon piece on the bottom.
