In the beaches of the Hague, there lives several species of Strandbeests... They look totally magical, and they only feed off of wind. Are they perhaps tame, distant relatives of Thestrals that had adapted to become visible to Muggles and magical people alike? Newt investigates their origins, and even has a chat with their apparent breeder, a Muggle named Theo Jansen.

(You should totally google strandbeests and Theo Jansen. Seriously.)
