Growing up I loved Stitch cause hey, it's Stitch! I also liked Tigger as a kid but as I got older I was more drawn to Eeyore. He and I have similar mindsets if you catch my drift.
I guess since DISNEY OWNS THEM NOW mine is Riso the rat from the muppet show cast.
The other would be the Ranger and Humphry the bear from the bonta vista wildlife films from the 60's
