From the mid-1950s into the 1960s Lagoon made many improvements. A showboat was added to the lake, and a new fun house was built, which featured such attractions as a multi-lane giant slide; mazes, mirrors, obstacle courses, and mystery rooms; a large turntable which flung its riders off at great velocity; revolving barrels; and the ubiquitous jets of air – activated by a human operator – which startled those who were unfortunate enough to stand over them. There was also a mini-car ride added in 1960, followed by the "Space Scrambler", spook house, I.Q. Zoo, and shooting gallery in 1961. The first Wild Mouse ride came in 1965.
