In this guide, you will get to know how to get through the Seafoam Island in Pokemon Let’s Go Pikachu & Eevee just by following the simple steps below.
You first need to enter the Seafoam cave and head directly to the right until you find this rock, as shown in the image below.
After that, you will need to push the rock down that hall and then follow it down. And if you don’t have the push yet, you go back to Fuchsia city and give the old warden his teeth. Now, you have to keep pushing it down all the way to the bottom.
You will need to avoid the pokemon, but they pop up sometimes, so get out of the way to catch them or pop a repel. Keep following to the bottom, and it will land in the water and start to block the current.
After that, head back to the entrance area and take the upper path this time; follow that around to the right to the block you are going to push it up and then get to the side of it and push it over like the first one. Push it down and follow the path, you will get to the bottom, and the current at bottom will be completely blocked.
Now you will be able to surf to get to the right side of the map, and you can also use that to get out.
Push the rock to the bottom by dragging it, and once you get down there in bust-out surf, you will need to stop and make sure to grab any of the items on the map. Just use the ladders to climb up to the top, and you will be able to get to Cinnabar Island just by surfing over to where the fire gym is.
