Go Go Hypergrind OST - Walkure (03)

Iggy Koopa (known as Hop Koopa in the DIC cartoons and occasionally as Icky Iggy)[1][2] is one of the Koopalings, a clan of seven siblings[3] that act as leaders of the Koopa Troop under Bowser (originally considered his children). Iggy is depicted as a crazed, mechanical genius and childish in personality when together with Lemmy Koopa. His two main outstanding physical characteristics are his glasses and light green hair (originally pink, light blue, and yellow). In later appearances, he is shown to be the thinnest of the Koopalings.
