S1E4 Tweenage Tycoons

Title: Tweenage Tycoons Plot: Tommy, Chuckie, Kimi, Phil, and Lil are determined to gather enough cash to attend a concert by their favorite band, "The Sulky Boys." However, their savings fall short. They convince Dil to market his latest creation, the "belt-quarium," designed for his new pet fish, Pablo. The belts become a massive hit, even though Angelica steals the concept. When the novelty fades, Tommy inadvertently pushes Dil to invent something new. As each trendy item quickly loses its appeal, Dil feels the mounting pressure to keep his friends and brother satisfied with fresh and innovative ideas.
