You won't be able to unsee it

So I don't know this figure except I've seen it a couple of times in no particular context and I always thought that it was supposed to be a mouth with 1 tooth, I didn't ever think of it as a nose when seeing it.

Today a lot of people learned that some always saw a nose, while others have always seen a mouth.

It's clearly a nose in this clip when Pikachu runs to Diglett.

I see it, but the curve and angle of the shine keeps shifting it back to a bulbous nose for me

its supposed to be a nose?

I had no idea that was a nose. I always thought it was a mouth.

I always assumed it was

But what if Diglett's nose was blue?
