In Pikmin: The Return of the Puffmin
The Splash Shreiker is the boss of the Sea Shelter, both appearing in Pikmin: The Return of the Puffmin. It is similar to the Waterwraith in the fact that it appears after a set amount of time in each sublevel and then travels about it, is invincible until the final sublevel, and instantly kills anything it rolls over. After two minutes have elapsed on the current sublevel, the Splash Shrieker will scream, fall to the ground from above, and then begin patrolling the sublevel by using its wheel-like feet. On the final sublevel, however, it will already be active. To fight it, at least one Pikmin must be tossed onto the ground as bait, the Splash Shrieker eventually seeing and chasing after it. The Pikmin will lure the Splash Shrieker to a nearby wall all by itself, dodging out of the way at the last second, the creature impacting the wall and its wheels breaking. Afterward, the Splash Shrieker will hop about its arena, completely helpless.
