Remember a terrifying monster pig is for life, not just for Christmas.

Ruby Rose was a guest on The Tonight Show and told Jimmy Fallon about what must be the worst case of buyer's regret in history. A few years ago she bought what she thought was a mini teacup pig for her mum. Turns out it wasn't so mini.

The pig is now enormous and aggressive. A young cousin even ended up in the emergency room after an encounter with the beast.
