change it to:

class Animal
   @temperature = 0

   def self.temperature
     @temperature
   end

   def info_temperature
     puts "My body temperature is "+self.class.temperature.to_s+" degree"
   end
end

class Spider < Animal
   @temperature = 20
end

class Horse < Animal
   @temperature = 38
end

batty = Spider.new
fury = Horse.new

batty.info_temperature
fury.info_temperature


the @@variables are not class object variables - they resemble static 
variables from in c++/java, it's not the same.
