Frogtown Mountain puppeteer, Eric Torbeck, shows some of the children at the Mexico Public Library’s final program for the season how puppets work. Librarian Valerie Messena said more than 120 youngsters participated in Captain Book and the Bookeroos during the past few weeks. The three children in the front row, from left, are Brianna Jones, 2, of Mexico, River Edmunds, 6, of Byron, and Jack Darling, 4, of Rumford. Frogtown is a professional puppeteering group out of Bar Harbor.
