sentences:  "Everyone's a Wally" was the first arcade adventure game to feature multiple playable characters - a revolutionary feature at the time.Players began in control of Wally (a builder and handyman), but could switch to Wilma (his wife), and their friends Tom (a punk plumber), Dick (a dodgy bricklayer) and Harry (a hippie electrician) - these last three names drawn from the placeholder phrase Tom, Dick and Harry.Herbert (their baby son) also appeared in the game as a mobile hazard NPC.
