A toy bubble-in-bubble assembly includes first and second coupled together bubble generators and first and second air supply conduits. The first gas supply conduit is positioned relative to the first bubble generator such that gas passing through the first air supply conduit impinges on the first bubble generator. The second gas supply conduit is positioned relative to the second bubble generator such that gas passing through the second gas supply conduit impinges on the second bubble generator. The openings in the first and second bubble generators are adjacent and positioned relative to each other such that a bubble generated at the opening in the first bubble generator is adjacent to an opening in the second bubble generator and thus enables the generated bubble to be blown into an opening in the second bubble generator to generate a bubble within a bubble.
