An only in Niigata keychain?

I thought this was too cute not to share! One of our friends here in Niigata is a rice farmer, and his daughter is elementary school aged. On her randoseru, she has the cutest keychain of a rice harvesting machine in a nice ode to her dad's profession!

I don't know that I've seen these keychains anywhere, but they feel very Niigata-specific and appropriate, since our local area is a koshihikari heartland. 

If you have kids (or work with kids) that have randoseru, have you seen any unique keychains on them that feel regionally-specific?
