Flowers that attack

Elston can ignore spiders and dead snakes but fallen sunflower stalks? Not so much.

Imagine the following scene:

Dog walking across street. Stops. Refuses to finish crossing the street.

Owner crosses street and starts to proceed down the sidewalk. Tries pulling the dog. Dog reluctantly starts to walk down the street but not coming anywhere near the sidewalk. Owner is screeching at dog because she is in the street.

Dog growls. Owner looks and sees 3 sunflower stalks fallen on the sidewalk.

Owner laughs. Dog tentatively walks past the scary sunflowers with a few more growls and then gets on the sidewalk once owner has cleared the area.
