This is too easy

The environment changes, so once previous favorable mutations become unfavorable.
Wouldn't a deformed fish or sea creature be at a huge disadvantage physically compared to its peers?
Yes, which is why there aren't thousands of species of deformed fish out there. They don't pass down the genes.
I just can't envision how the mutation could keep progressing while it wasn't working and while it wasn't helping the creature in any
Because the genes are not dominant in the species at the time. Random mutations happen every time a creature is conceived. When you have thousands
of generations, each of which consists of thousands of individuals, differences will eventually emerge, depending on who passes down what genes and
which are favorable. It could be a more sexually appealing trait, or it could be a survival mechanism. I don't think you realize that there are tons
of mutations that are not noticeable at all. They could be dormant for years until they combine with another mutation and cause a change that one
could detect. The mutations do keep happening, but the environment decides which ones stay and which ones go the way of the dodo.
It just came to be one day after all sorts of crazy mutations and strangely formed inners? One day it just started to function? Even while its
normal peers weren't burdened by these crazy mutations going on inside the body?
For the most part, the changes are small, but they add up
over time. It's not like you'd notice it from generation to generation, or would even notice it in your lifetime. You'd need thousands to millions
of generations to invoke a change on that scale. They didn't just magically emerge. They slowly changed over time.
