(opening credits) In association with a bunch of other guys too numerous to mention...
There's a post-credits scene in which we see Ika Chu sulking in prison, while he anticipates the movie's sequel.
When the movie's title is shown on the screen it gets crashed by the characters and some are lying. A cat gets the R crushed on the head and asks "Where did this come from" to which another cat says "The title department".
The closing credits feature scenes from the movie appearing in origami style.
