Explanation: Nosepass are only able to point in one direction, restricting their movement. This one wishes he could fly like Metang, but he cannot, so he is sad. Nonetheless, he won't give up, so he refuses to move from this hillside as the moss grows on him as he stargazes.

My immediate thought upon seeing this in the bitpack: "Oh neat, it's DimWiddy's entry"

Also my interpretation is that Metang is just forcing Nosepass's face upward

Nice work! I find it hard to believe that's a "real" pokemon though. Have I become old or something?!

Metang and Nosepass! They were introduced three generations ago, geezer!
