I've always perceived Bowyer as if he were a hybrid between a bow weapon and a fuzzy catepillar enemy, as if related to a Wiggler, veiwing the string on his tail as a silken strand.
One day I had the thought of if he were to spin a cocoon out of his bow silk and metamorphasize into a moth.
The log reflects how he would look if that were to happen, and how he'd use his wings to shoot arrows instead.
