Comments.Text: Look closely at the dino's head. Here you can see little aperture that splits T-rex's upper jaw on half. On this picture I'm showing you what I mean. https://i.sstatic.net/Bfd4v.jpg I think that's the "ticket" to replace battery without destruction, isn't it? Just use pocket knife to open. Will it work?

  Unfortunately after attacking this piece from every angle with some plastic opening tools, I'm quite certain there is no non-destructive way to open this piece.
  
  I tried slipping a spudger in every seam where the plastic joins and was unable to find anywhere I could get any leverage, or even push it in more than a few millimeters.
  
  Even the jaw piece is held on by a cylinder of plastic running from cheek to cheek. There isn't a good way to photograph it, but here's an illustration to show you what I mean.
