SPOILER: There is a scene at the end of the closing credits: Jonny 2X4 and Plank become the villains the Gourd and Timber the Dark Shard, but Jonny learns there's no time as it's the end of the movie.
The a.k.a. cartoon logo that follows has a melon background, reflecting Jonny's melon-themed alter ego.
The opening titles appear in a montage of scenes of the cul-de-sac, showing the latest scam.
