Howling:Slitheen in SJA S4

In The Nightmare Man a Raxacoricofallapatorian appeared. In the credits it was listed as a Slitheen family member, but I don't think it was. It was a much darker colour of green all over, and not light green with a light belly. Can we say that it was if it was so obviously different? --The Thirteenth Doctor 12:31, October 12, 2010 (UTC)
