This page offers a guide on grabbing the Shine Sprite in Episode 3 of Ricco Harbor. This area is accessed via the Rainbow M on the side of the Boathouse on the west side of Delfino Plaza once you’ve obtained at least 3 Shines and defeated the Polluted Piranha.
Gooper Blooper strikes again
In order to reach Gooper Blooper’s location for a second time, you’ll first need to acquire the Rocket Nozzle, you can find this by using the nearby sewer and follow it to the first intersection, heading left to exit it. From here, drop to the house to your right and then use a Side Somersault to gain height before using your FLUDD to hover over to the next building, here you’ll find a box with the Hover Nozzle. With this in hand, make your way to where you fought Gooper Blooper back in Episode 1 and then use the Rocket Nozzle to blast over to the helipad where your old foe awaits.
This battle follows the exact same strategy as your initial tussle with it in Episode 1. You’ll need to evade the tentacles and then pull them off with the Y button and allow you to gain access to it’s mouth, pulling it back to deal direct damage. There is one slight variation to this battle, at times, Gooper Blooper will spin around with whatever remaining tentacles he has to deal damage so be ready to leap over them at any given moment. With Gooper Blooper’s defeat for a second time, another Shine is waiting to be claimed!
