Rugrats (1991)

Season 3: Episode 45

After being disgusted by a competitor's toy commercial on TV (a ""Transformer""-type flying bird that flies, goes in space, does your homework, etc.), Stu throws his invention (similar to what's on the commercial, except it doesn't do anything) at the TV, breaking the TV and the bird (the latter already broken to begin with). Afterwards, the Rugrats use a box (a ""Cheese of the Month"" box that was to be used to ship the TV back to Japan) to make their own shows, all making a rather colorful lineup.
