Walkthrough: After defeating Mechawiggler, Bowser will once again escape as New Donk City will return to its previous state. Before heading down the Spark Pylon, you can find another Power Moon within a hole by the red girder. With nothing better to do after obtaining it, try checking in with Pauline in the City Plaza. The now busy streets of the city will be full of people and taxis, with a lot more to see and obtain this time around.
As you head to City Plaza, join the jump rope contest in the grassy area on the right to nab another Power Moon. After doing so, head to the Crazy Cap Store. There should be a man there playing with a remote control car, the saem you can use Cappy to capture and control to earn yet another Power Moon. After obtaining those two easy Power Moons, head down Cranky Avenue to reach the City Plaza and chat with Pauline.
