I read that its a glitch and the glitch has been there a while and don't know why all of a sudden its visible.
c'mon people, is just a glitch , tnt normally anounce plots in magazines or NT, wait to monday when TNT starts to work, and they will see that is there a neopet that costo 51 mill to adopt, which has no stats, no name, and either no specie (Blue Grundos are the default pet ..., if there are no pet the blue grundo will appear), and they will destroy it *0*
