Last night, Shannon and I were in the kitchen with all of the greys. The rest of the parrots were in the living room with Thomas. All of a sudden, we hear Rocky singing. This went on for over a minute, so we went into the living room.
He was in Beeps's cage tray, singing and dancing. He put on quite the show, and had us all laughing. It was clear that he was trying to sing words, but we couldn't understand him.
Later, Thomas told me that Rocky had asked him for some of Thomas's oatmeal dessert. Thomas said no, as Rocky had poop on his beak from playing in Beeps's cage tray. So Rocky had to sing the blues.
