I was gonna guess:
Fiesta Picnic or Old Flossy's Day Out
Happy Heatwave (looks a lot like Happy Slappy)
Down By the Lagoon (though Down the River We Go is close to looking like this)
OMG! I just looked at the playfields and made up names before I read any of the answers! I can't believe how close I really was on them. One of the things that cracks me up about the older pinball machines are their names / themes.
