Arthur is very inquisitive and always wants to know what’s going on. Wily and clever, he is the fixer of the group, miraculously managing to find the things they need. No one knows quite how he does it, but I think we can guess. With that long proboscis of his he can sniff out any item likely to become useful at some later time. However, the items he gets don't always work quite as they should. He plays the banjo in the band, and is very good too.
