Well there are some clues regarding the puzzle.

The capitals of most if not all colors by my understanding refers to Porky Pig, except blue and black and the music also refers to it.
So either Porky Pig or what he stutters "That's all Folks!" has to do something with the next steps.

The picture has the ori ending in its name that refers it is original and so I think it must be encrypted with xor method (standard picture encryption) with a key.

So I tried to use these Porky and That's all Folks phrases (excluding spaces, capitals, with small letters also) and many iterations of them (as plain text, sha256 hashes, sha256 hash to ripemd160 hashes), to encrypt the 'original' png.

Sometimes I got blackish pngs but nothing else.

Finally I gave up, I share my thinking so it could help someone.
