Anti-Wanda also gave birth to Foop here in the episode, "Anti-Poof". The sign over the castle's entrance says "Anti-Cosmo's Castle Welcome. Not!"


The castle is colored black and dark blue, with sharp spiked towers and a purplish colored Rainbow Bridge covered with spines. The castle is usually seen surrounded by dark or red ominous clouds.

Anti-Cosmo's castle first appeared in "Fairly Odd Baby", where Anti-Cosmo was seen plotting alongside his fellow Anti-Fairies. It was also seen as a fish bowl version in "The Fairly Oddlympics" The castle was also seen in "Anti-Poof" where Anti-Cosmo was despising the fact that Fairies are worshipped for their accomplishments while Anti-Fairies don't get any of that. Anti-Cosmo was also despising the fact that there was no Anti-Poof despite that there should be an Anti-Fairy for every Fairy. After seeing some of the strange traits that Anti-Wanda was going through, Anti-Cosmo realized that Anti-Wanda was going to have a baby. This led to Foop being born which Wanda was able to sense due to her motherly instincts.
