Opens Wednesday: In the past decade, Cirque du Soleil has brought shows to the riverfronts in Minneapolis and St. Paul, to Parade Stadium, even Target Center. The Canadian troupe's latest themed spectacle will take place in a tent in the north parking lot at the Mall of America. "Ovo" (egg) is set in a fanciful, bio-diverse world of gymnastic fleas and ants that juggle kiwi-like slices with their feet. The insects, curious, fiery and frolicsome, become agog when an egg appears in their midst.
