Call them what you will. Summer, Seasonal, Outdoor or as we used to call them, Beach toys. These were the cheapo toys especially made for vacation fun. And usually they never lasted til Fall. I'm talking about Vinyl toys like the Pale and Shovel, Sand molds and boats and vehicles that pop up on toy shelves around Spring.
This is one for example. Though this particular one was aimed at the Barbie color scheme. The dune buggy was suspiciously scaled to fit the GI Joe, Big Jim and Mego scales.
In my experience. We spent our Summers at a PA lake named Canadohta. Soon after arriving at our rental cottage. We would head out for supplies. That's when it was imperative to get the Beach toy to make Summer Great!!!
