Good day to you. Here is Mr Rex. He was one of the many characters from the series Amazing Animals for the Disney Channel. Amazing Animals was a live action series with a CG computer lizard as it's host. Every episode there was 4 times 40second 2D shorts in it which we did the animation. Mr Rex was one of the recurring characters. He was my favourite as we made him into a little softy really.
Oh as a side note, the pegs were at the top as he was a panning level (which the BG panned through shot behind him on bottom pegs). When we would animate the pegs would always be at the bottom of a page. It makes flicking the pages easer.
