New West Theatre’s theatre for young adults presentation of “Peg and the Yeti,” should be called Peg and the most patient parents in the world. It runs at the Sterndale Bennett Theatre until Jan. 5.

 It begins a with soft Celtic music playing as a few members of the audience in the front rows are issued ponchos to go with the Maritime setting.

  The tight, three member cast of Geneviéve Paré (Mom), Cari Russell (Peg) and  Jed Tomlinson (dad) reinterpret the children’s tale with subtle skill and get the audience involved in an hour long journey though Peg’s over-active imagination.

  The family lives on a fishing boat, which could be stultifying for many a young person. But not Peg, who embraces it, bounding all over the stage with childlike enthusiasm.
 She climbs all over the stage, climbs to the top of the sail, imagining she sees Mount Everest and she’s off as she takes her parents along for the ride.

 No fishing will be done today as they travel to Mount Everest through a variety of methods. And her parents, good sports as always, supply the sound effects and smoothly shift pieces of the set to reflect whatever Peg imagines. They also play a variety of characters she meets like Scottish mountain climbers, and, yes, the Yeti. Paré and Tomlinson lose themselves in their roles so much, that they become prominent parts of Peg’s imagination rather than just endlessly patient parents playing with their child. Cari Russell’s  contagious, childlike enthusiasm comes naturally. She is just adorable. The audience gets just excited as she does on her adventures.

The parents will come back to set Peg straight, when Peg loses her temper because  the avalanche  she asks them to create isn’t big enough. This is where a much of the audience participation comes in. While the audience  is asked to sing and make a few sound effects like a train whistle and wheels, the kids  in the ponchos are asked to come on stage to create a huge avalanche, and Peg’s parents make sure she thanks them for their help.
 “Peg and the Yeti is a  lot of fun for parents, kids and big kids. It’s interactive and a great way to blow away those winter blahs. It runs Jan. 2 at 3:30 p.m., Jan. 3 at 1 p.m. and 3:30 p.m., Jan. 4 at 7 p.m. and  ends Jan. 5 at 1 p.m. and 3:30 p.m.
