This is the Pink Fairy Armadillo.

They live in Argentina, have a furry bum to help them thermoregulate, and are around 3-4 inches long. It is said they can burrow through sand as fast as a fish can swim.

You're welcome.

@RussInCheshire I found out these exist a few months ago when a friend asked me to draw one! There may have been a (not entirely unintentional) misunderstanding along the way...
