So, I was chatting to this pig down in West Spice. He was regaling me with tales of parties and the like, but wandered off while he was in mid-sentence. He wandered off the edge of the screen, most of the speech bubble remained, but a chunk of the speech bubble disappeared off the edge which made it rather hard to decipher. I tried to follow him, but couldn't move until the conversation was over.
