I was biking down a country road I used to live on, I think I was 8 or 9, and on my way home I saw this small humanoid looking being run across the road, from one crop field into a corn field.
The only details I could make out, and I still vividly remember, was that it was completely covered in yellow, from neck to feet, and I think it has green on it's head. I told my mom about it and all she could come up with was something about cabbage patch kids.
Never saw that thing again, but I still think about it from time to time
Edit: it was the size of a small child, about 50 feet away
