My all-time favorite cartoon character would have to be Squidward Tentacles. There's just something about his dry wit, sarcasm, and overall grumpiness that I find absolutely endearing. Despite his often pessimistic outlook on life, Squidward is a complex character who has moments of vulnerability and even kindness. His passion for the arts and his dreams of becoming a famous musician also make him a relatable and sympathetic figure. Plus, his interactions with SpongeBob and Patrick always provide comedic gold. Whether he's playing his clarinet, working at the Krusty Krab, or simply trying to find some peace and quiet, Squidward never fails to make me laugh. So, yeah, I have to say that Squidward Tentacles is definitely my all-time favorite cartoon character.
