I've only killed two small animals; one was a mouse, i crushed it with my shoe because my friends mom told us to get it out of the kitchen and kill it cause the cat was tearing off limbs and slowly torturing it to death. It was a gnarly feeling its bones crush under my shoe. The other one was a baby gosling it was a total accident. I threw this hard chunk of wood at the mom canadian goose cause it was chasing us unprovoked for no reason for like 3 minutes, missed the mom and it hit one of the babies in the neck totally destroying its neck. The mom goose made this hissing noise for like 2 minutes and looked like some kind of demented possesed demon, then dragged it into the water, and get this shit man, a fucking seagull who had been watching the whole thing, swooped in and swallowed the dead baby WHOLE dude, like for real lol it was the craziest thing me and my friend ever saw it was sitting there choking it down while the mom goose was pecking at it and trying to hurt it, but it just ignored it til it choked the entire thing down. The baby gosling was as big as the seagulls entire body, so the seagull looked totally distended and was doing this weird choking thing, and couldnt fly away, the mom goose kept pecking at it. Of course we were laughing hysterically the whole entire time i mean how else are you supposed to react to something like that. Then some guy across the street from that duwamish river park was like "YOU FUCKING PIECE OF SHIT KIDS, I CALLED THE COPS ON YOU, DONT EVER FUCKING COME BACK TO MY PARK" and we threw beer bottles at him then ran away.
This is a 100% true story.
