If I understood correctly you want to generate a set of files, that are
YAML exports of arrays, each of them containing a list of URLs that are
composed of a prefix, a pet name and a pet color. For each pet, you need
all color combinations. Is that right?

If that's correct, then you don't need to have a different array,
named as the pet you are actually processing. The only places where
you need the name of the pet are when creating the URL, and when
calculating the name of the file. The name of the variable that's referencing
the array is not relevant. I don't understand what error are you getting
(when removing the * from your code), it works for me. This also works
for me, with some
cosmetic changes (string interpolation), and requiring yaml.

require 'yaml'
$defout.sync=true

petpets = ["Slorg", "Sludgy", "Spyder", "Wadjet", "Buzzer", "Angelpuss",
"Mallard", "Scarabug", "Cobrall", "Magaral", "Tenna", "Floud",
"Slymook", "Stego", "Selket", "Warf", "Altachuck", "Khnum", "Blobagus",
"Tomamu", "Psimouse", "Puppyblew", "Hopso", "Harris"]

colors = ["black", "blue", "brown", "chocolate", "christmas", "clay",
"cloud", "custard", "darigan", "disco", "dung", "faerie", "fire",
"ghost", "glow", "gold", "green", "grey", "halloween", "ice",
"invisible", "island", "jelly", "maraquan", "mutant", "orange", "pink",
"pirate", "plushie", "purple", "rainbow", "red", "robot", "sketch",
"snow", "spotted", "starry", "tyrannian", "white", "yellow"]

petpets.each do |petpet|

  puts "Now creating file for " + petpet.to_s + "."

#  *petpet*_array = []
   petpet_array = []

  colors.each do |color|

#    url = "http://www.mysite.com/code/" + petpet.to_s + "_" +
color.to_s + ".gif"
       url = "http://www.mysite.com/code/#{petpet}_#{color}.gif"

    puts url

#    *petpet*_array.push url
      petpet_array.push url

  end

#  File.open("/Users/superfly/Desktop/news_finder/arrays/" +
*petpet*.to_s + "_array.yaml","w") do |out|

  File.open("/Users/superfly/Desktop/news_finder/arrays/#{petpet}_array.yaml","w")
do |out|
#      out << *petpet*_array.to_yaml
         out << petpet_array.to_yaml
    end

    puts "The file for #{petpet} has been created  successfually."
    puts ""
    puts ""

 end


If I'm completely misundersting, please let me know, with some examples of
what you need as the output and what are the errors you are experiencing.

Hope this helps,

Jesus.
