The pictures you can see on Twitter are all cute "turtle bananas," including one with a parakeet head growing out of a banana, and another with a banana skin sticking out of a parakeet head. According to @iichiko_hanaPC, who posted the photos, he processed his cockatiel "Hana (♂)" and the banana using photo editing software on his PC.
[! --A cockatiel is a small bird. They're yellow. And bananas are yellow, too. That's it. Cockatoo = banana. I'm really hungry. Let's eat... pic.twitter.com/oQLr4Widg0
