Of course the Invisible pets have to be released at some point, I just think that they should avoid releasing Invisible as the only new colour for a pet day. The pets are the main purpose of Neopets after all, and each pet day should be given the proper time and effort. I can understand this being difficult at times, and I`m sure TNT has got plenty of things to do behind the scenes... And it`s not like Invisible doesn`t require any effort at all, but they should have given Tonus a second colour in my opinion.
