I don’t have a suggestion for a name, but I do have some other suggestions.
First, I think his arms are way too thin. They are proportioned like a more realistic human-ish character and they don’t really match the rest of him. Look at Gumby’s arms for inspiration.
Secondly, as short and stumpy as his legs are he might not even need knees, but I haven’t seen him posed so he may need them.
I like the character’s face. Make a scene with it.
