You don't say HOW it's not working.

I'm guessing that it's here, since you've defined initialize to
require two parameters and you aren't supplying any.

If that's the case try either

animal = Animal.new("purple", "teeny-weeny")

or make the arguments optional by providing defaults like:

def initialize(color='transparent', size='medium')
    @color = color
    @size = size
 end

or even

def initialize(color=nil, size=nil)
...

If you want to allow nil as an initial value.
