Chip 'n Dale are animated chipmunk characters created by Walt Disney Productions. They first appeared in the 1943 cartoon "Private Pluto" and quickly became popular for their mischievous antics and playful rivalry with other characters, particularly Donald Duck and Pluto. The duo is known for their distinct personalities: Chip is the clever and resourceful leader, while Dale is more laid-back and goofy. Over the years, they have starred in various cartoons, including the popular series Chip 'n Dale: Rescue Rangers, where they work as detectives solving mysteries alongside their friends.
