Po couldn't take it anymore. Her family is dead. She was one of the main four Teletubbies, Tinky Winky, Dipsy, Laa-Laa and her. However. Before this mess happened. Po had to fix the custard machine and gave some to each of them but she didn't have any. Later during the night. Tinky Winky broke the machine and walked away. Po woke up and searched for him but he was different. His skin was gray and he had pitch black eyes as he screamed at her. She ran to the house and found Dipsy's decapitated dead body. She kept running till Tinky Winky got distracted...She couldn't take it anymore. She left the mainland out of fear. Now she's walking along a path.
Po: "Tinky Winky killed Dipsy...maybe Laa-Laa since I didn't see her. What if I'm the only normal one. What chance do I have? I'm scared. I want everything back to normal. But it's not going to happen."
