This may sound wrong, but..

Obviously, it would look a lot better in real life, but since I never had a Hank, I have to edit an image of one (though it isn't a perfect illustration).

If I did have what was required to make it for real, I probably would've copied the chasing Dementor idea from the version that inspired it.

In the meantime, I could probably make a fully reversible "disguise" for my Talking James and have him run while decorated to look like it (even though it would obviously still have James' voice and whistle sound).
