A crash-landed spaceman and beached whale named Martha make sensible companions under the glow of golden Christmas lights.

This oddball participatory comedy crafted by Seth Soulstein is a two-hander, although the crane makes three.

Clad in silver spandex, a wide-eyed Soulstein proves his improvising chops. Never does he break character—even when a wayward space egg nicks a nearby car. (In the universe of public drama, one has to be prepared for anything).
