Christmas cracker monster

Here is a monster for you, courtesy my niece’s Christmas cracker:

Q: What do you get when you cross an octopus with a cow?

A: A farm animal that can milk itself.

I thought briefly about including some stats but the mind boggles. A black and white dappled octopus the size of a cow that squirts a cloud of milk at you as it escapes? A cow with tentacles for legs that climbs up the side of the barn and turns the same colour as the wood? Either way, roll initiative!
