El-Fish (PC)

A hint on how to create some really weird mutations
and have fun doing so :

El-Fish stores its fish as roe in binary files.
When you click on Restore, the software converts a
roe file back into a fish. But you can also
convert almost any binary or ASCII File-a customer
database, a budget spreadsheet, a health-benefits
memo into a fish. Just copy the file with new
extension .ROE. (Don't use EXE or COM Files.)

After loading El-Fish, Click on Restore From and
find the fishy new file. It will create one or
more mutant aquatic life forms. I tried a file
containing Earned Run Average statistics for
American League pitchers, and as expected,
the fish created was extremely ugly.
