Flowing Skeeterskate

The Flowing Skeeterskate is a spitterspatter appearing in Pikmin Eco II as the first boss of the game. It is a quadrupedal species related to the Skeeterskate and is about four times the size of its water-skating relative. It has four eyes, two small and two large, and a snout ending in a spiked mouth. Its abdomen is encased in membranes, like a cage.

Strategy
Being the first boss of the game, the Flowing Skeeterskate is notably weaker than other bosses. It will wander around the main area where it is found, its feet able to stomp Pikmin that get too close. Occasionally it will stop and drink up the water in its arena and will use it against Pikmin and leaders. It will also occasionally release all of the water in its abdomen at once, flooding the arena completely aside from a few small areas. Blue Pikmin can easily swarm the Flowing Skeeterskate after this happens and damage it that way. It is possible to burst its abdomen before it releases the water to deal extra damage, but it immediately fills up the arena doing this, so this will most likely drown any non-Blue Pikmin.

In-game notes

 * "A much larger and robust relative to its pond-skating cousins, it has lost its ability to skate on water for the standard walk around on land. Its abdomen can withstand up to twice its own body weight in water, most likely as a means of incubating its fully-aquatic offspring. It's interesting to think that a creature so specialized in water would come back to land again. Maybe it misses the soft dirt under its feet?'"
