Hooking the nuclear submarine wasn't the end of it.
Rather, the burden that followed was even heavier.
The remaining Mushroom Eggs were surely scattered across various places on the ocean floor, making them not easy to hook, and no one knew where they could be found.
The difficulty of this task was likely even greater than that of the nuclear submarine, given the sheer quantity involved—it wasn't just one or two.
Fortunately, they had managed to hook quite a few earlier, leaving about eight more to find.
However, the difficulty of these eight was definitely higher than before, and even harder to find, as their distribution was unknown.
