Waddlepus

The Waddlepus is a generally passive flobbler. They are always found sleeping on land or in water, and wake up only when Pikmin or leaders are nearby. Once disturbed, the Waddlepus will inflate itself and slowly waddle towards them. If Pikmin are latched onto the Waddlepus when it inflates, they will be thrown off. Once inflated, the Waddlepus will then shoot out a stream of bubbles from either its mouth or from the pores on its back, deflating in the process.

In Pikmin: Decayed Leaf
The Waddlepus is a returning enemy in Pikmin: Decayed Leaf. The creature takes on its original appearance throughout the Pikmin games. The Waddlepus will never move when idle; preferring to stay asleep. Even when approached, it will not attack. If attacked; however, it will extend its head and begin to emit dozens of bubbles. These bubbles will trap Pikmin unless popped by other Pikmin; preferably Winged Pikmin. Aside from that, it cannot kill Pikmin. When defeated, it will spit out 50 bubbles all around it and squeeze out a small pool of harmless ink before dying. A Waddlepus is harmless, but can scatter your squad into chaos if provoked.

In Pikmin: Attack of the Breadbugs
The Waddlepus appears in Pikmin: Attack of the Breadbugs, encountered in the Marsh Territory. It can blow bubbles to trap Pikmin and Captain Olimar in. Along with that ability, it has a new one: squirting ink to distract attackers. When sprayed with ink, Pikmin will simply stand in place as they would if they did not have a task. While the Pikmin are distracted, the Waddlepus will retreat. Waddlepi are always found in water, and thus can only be attacked by Blue Pikmin. Waddlepi will rarely be willing to leave any body of water.
