Another marvelous sculptor of clay animation, Will has made many classic creations of his own. One of his earlier, traditional creations include the famous "California Raisins". Will also made other fanciful creations such as "The Adventures of Mark Twain". The story depicts the author's journey in a riverboat-cum-hot air balloon to meet up with Haley's comet. Also aboard teh vessel were three stowaways, Tom Sawyer, Huck Finn and Becky Thatcher, whose presence enabled Twain to tell them such stories as The Celebrated Jumping Frog of Calaveras County and The Diary of Adam and Eve (which was incorporated into the story).

Will also went on to create to famous duo of popular chocolate treat M&Ms. Yes indeed, he was the father or Red and Yellow. Most people knows these brilliant characters from many television commercials, and on the wrapper of the popular chocolate.
