The mischievous menagerie from Click, Clack, Moo: Cows That Type are back, this time with plans to dupe their gullible caretaker, a city-boy accountant, when Farmer Brown goes on vacation. While he's away the cow, chicken, pig, and duck play--and eat pizza (not the frozen kind). Way more intelligent than your average children's fare, adapter James E. Grote's book beefs up Doreen Cronin's simple story with a comical farm-family dynamic, delivering laughs for kids and parents alike. George Howe's blues, gospel, and bebop rhythms set the barnyard jumping, and the well-synchronized ensemble grooves to his resonant harmonies. Director Shole Milos and scenic designer Alan Donahue make efficient use of Lifeline's little stage, creating a colorful, fanciful space complete with bubbles cascading from the ceiling during the pig's bath and allowing for more frolicking per square foot than you'd think possible. Altogether very aMOOsing. Through 6/19: Sat 11 AM and 1 PM, Sun 1 PM. Lifeline Theatre, 6912 N. Glenwood, 773-761-4477. $9 in advance; "pay what you can" at the door.
