As a child, my family used to have a large fish tank with a family of piranhas inside. When the females got pregnant, their bellies would swell as expected, but they were nonetheless dangerous, especially when hungry. We used to have to feed them whole turkey legs & other items about that size every couple days. One holiday, we went out of town & the teenager that was supposed to feed them for us got stoned, ate the food that was meant for the piranhas & never came back. When we got home, we found that they'd turned to cannibalism & only 1 was left wounded but alive. So don't underestimate something deadly, just because of a single negative attribute that might seem like a weakness.
