How to Get Submarine in Fisch

In this video I show you exactly how to get Submarine in Fisch Roblox, including the construction route, the secret code you need, and how to actually use the sub once you’ve unlocked it.

You’ll see why buying the Submarine outright isn’t recommended, how to start the Submarine Construction quest, where to go, and how to input the temporarysubmarine code to grab your parts quickly. Then we’ll build it, talk to Dr Glimmerfin, and I’ll show you how to board, descend, ascend, and exit the Submarine properly.
