Stilting Unicorns, baton twirling Purple People Eaters, juggling werewolves, and hula hooping elves are among the “Mythical Creatures” expected to appear at Nunziato Park near Union Square in Somerville this weekend.

The OPENAIR Circus presents “Mythical Creatures,” where students of circus arts show off what they’ve learned in summer classes.

You’re invited to watch the show on Friday, August 1, at 6:30 pm, and on Saturday and Sunday, August 2 and 3, at 2:30 pm. There is no admission fee, but donations are welcome.

Since the performance will be in the open park, blankets and folding chairs are encouraged.

For 40 years, children, youth, and adults have enjoyed OPENAIR summer classes and shows, as well as parades and festivals.
