She was playing in Gidget goes to Rome.

Is Alma the one that Beaver gave the rat or frog to in the box? He rang the doorbell and gave it to her or ran away?

I'm not 100 percent sure but I think that was an earlier episode and the girl in that one was named Penny (not the later Penny, but a girlfriend for Wally)

Alma was the one with the snobby mother (played by Jean VanderPyl) and the father who smoked a pipe, said virtually nothing, and stood by the fireplace.
