Recently while playing minecraft I decided to take one of my parrots to the nether with me as I didn't want to take the time to remove him from my shoulder. As I went to leave the nether I noticed that my portal was not working. I tried breaking my portal and rebuidling it, but that did not work. The only way I could leave the nether was to remove my parrot from my shoulder, and now it is trapped in the nether.
