Now to go through Lake Rocky one last time. This time, you should definitely equip the Proton Torpedo and Mine to the Sea Fox. Most anything else for it is up to you.
———-
In the second section of Lake Rocky, go to a thin row of rocks and blast through them with a mine. The leads Tails into one more path he can take in this lake. As you go deeper through here, more of the terrain turns magenta, and Tails will be threatened with cannons.
In the next section beyond this, Tails will now be going through some kind of deep-sea terminal. At the end of it will be much bigger cannon that shoots enemies at you. THAT’S when you gotta blow it up with the Proton Torpedo. This will lead into a third section of this area.
From there, just keep rising up to the surface, and eventually Tails will pop out of his sub to finally reach Coco Island.
———-
From there, you should have the Remote Robot and the Triple Bomb at the ready for Coco Island. Anything else is extra.
Coco Island will first have you navigate a maze, using the Remote Robot to pick up blue switches to turn off force fields so that Tails can go further.
The blocks that point down should mostly be avoided. If Tails drops through these, he can’t fly back up through them, making you waste some time in getting through this area.
Within this same area, you can find the Green Chaos Emerald. This is the final one out of the six you can find in this game, and will show this by giving Tails 99 Ring HP when you pick it up.
———-
At the bottom of the next section, there will be a hole in the row of spikes. Follow it to reach the Teleport Device. This will let Tails instantly return back to his house for a quick escape from death, or just to saving time to leaving the area on foot.
Besides that, this section is more of using the Remote Robot to help Tails disable force fields so he can keep going through this fortress.
———-
The last section of Coco Island has you in a boss fight against Doctor Fukurokov… but it’s not really much of a fight. He just drops Tails through a trapdoor and lets his security robots deal with him.
To defeat this doc, you’ll have to take the Remote Robot and a little course to fly back up to where Fukurokov is. Apparently… there’s a rock above where he is…
Just… drop it on him, and he’s immediately done! Return to Tails, and then you can just exit stage left, where Tails will then make a hasty retreat from Coco Island with his Sea Fox.
And now to head for the final area in the whole game!

That was very good! I hope to the final part to this game, my dude.
