The one where he is wearing a top hat in the bottom right corner

And is it based off of a manga/anime since a lot of his characters are?

Or am I completely wrong and he's just modeling ;_;

EDIT: I would also like to know the one with him and the skateboard 😃 Thanks!

here he is on wikipedia, it has a list of his films and stuff, you could try googling for images from those movies and see which one matches the characters you're looking for.

Feed your head.

Thanks, i'll try that!
