I'm not entirely sure, but I think your Rogues are those giant pumpkins, right? My guess is that your pumpkins started getting heavy and needed more support. A dog, cat, squirrel or rabbit could've been messing around with the fruit or vines and it detached. Heavy winds or rain could've caused it as well. Your little pumpkins are a bit easier to solve. Usually when a fruit or vegetable starts splitting like that, it's due to erratic watering or a sudden change in the temperature.
