Here's a short vid of Raz talking. Since getting Nemo he hasn't spoken very much but he did recently. I only have my phone (it's not great quality) so I couldn't put any subtitles or increase the volume.
Some of the things he says in the vid:
He's learning to sing the cops theme song (changed a bit): "Bad birds, bad birds, whatcha gonna do when they come for you". He also says: "whatcha doing", "hey Raz", "I live with Sharday", "Silly budgie". He says a few other things in the vid but those are the main ones .
