I did this character some years ago, the lack of references didn't help any. By the time I liked how he turned out, it was time to send an email to the company. Unfortunately, before I could even do that..they came out with their own version. Talk about timing, the worst thing, the kangaroo has lost a lot of his character and personality. To me, it just looks like a giant green rat that just came out of weight watchers.
Also, the funniness in the ads died as well. Why is that, when a 2d character becomes 3d, all past history is wiped away. For some reason...it has to act and move like a human, when it never did before...where is the fun in that :)
