It's haggis fighting actually! Although that sometimes involves some rolling about. Bloody things are hard to kill!

Except you don't put Offal in those Haggis? Or maybe just a higher % of cartilage and bone. Grim!

It's all heart, like literally :0D

And those valve'y bits you get in arteries. Chewed on plenty of them. Kinda look like mouse's ears!!
