While not often ranked among the most popular, the Fisher-Price Little People #2525 Playground stands out as one of the better-designed toys from the challenging late 1980s era. Unlike many sets of that time made with softer plastics, this playground’s base was crafted from durable hard plastic, offering greater sturdiness. It features familiar favorites like the swing and merry-go-round borrowed from the #923 School set, alongside its unique and highly sought-after exclusive piece: the square blue climbing cube, which remains one of the rarest and hardest parts to find.
