The Galaxy Explorer Helmet is a legendary pet accessory in Adopt Me! that could be obtained from finding the 5 items from the Sing 2 update (Ash’s Guitar, Jonny's Jacket, Miss Crawly's Eye Ball, Meena's Microphone, and Gunter's Dance Suit). The Galaxy Explorer Helmet is now only obtainable through trading.
The Galaxy Explorer Helmet features an animated space helmet topped with a gray ring. It has a purple tint and four planets circling it. The first planet is yellow with darker yellow spots and a peach-colored ring, resembling that of the planet Saturn. The second planet has light blue and white streaks with a blue surface. The third planet is fiery red with craters and the whole planet closely resembles the planet Mars. The fourth planet resembles the second planet, except that it features blue, pink, and green streaks with yellow spots all around.
