While there have been many cartoon characters honored with stars on the Walk of Fame, the designation generally goes to the creators and voice actors behind the characters.
Here are some examples:
* Walt Disney: He was the first cartoonist to receive a star on the Walk of Fame in 1960.
* Mickey Mouse: Mickey Mouse received a star in 1978, but it was awarded to Walt Disney, the creator, rather than the character itself.
* Bugs Bunny: Bugs Bunny's star was awarded to Mel Blanc, the voice actor, in 1985.
Therefore, there isn't a single cartoon character that holds the distinction of being the first to have a star on the Walk of Fame. The Walk of Fame recognizes individual achievements, not characters themselves.
