Did you know that...
- PaRappa was originally drawn as a variety of species, including a shrimp before being turned into a dog?
- General Potter was going to be an important character in the story, with him possibly even going to have a stage in the game between Fleaswallow and Cheap Cheap's, as shown in a note in his concept design.
- A character called Pony Pony was created around the same time as PJ, Sunny and Katy, but never actually made it into the game? However, she makes a cameo as a poster in PaRappa's bedroom, as well as in Club Fun's walls.
- There are quite the amount of unused graphics on the game, namely a model for PJ Berri in his normal appearance, a sprite of Joe Chin and front facing beaks for Cheap Cheap, which can be seen here.
- In addition, unused models, most notably for Katy but also for PJ can be seen in both beta and final versions of cutscenes on the game.
- One of the first showcases of PaRappa to the public was in 1996's Tokyo Game Show, in which it was very well recieved by the attendats and ended up stealing that year's show.
- The earliest known TV appeareance of PaRappa was on 1996, on the television show "Oh!". You can watch this show here.
- In Japan, the game released on the exact same day as the first Crash Bandicoot game, December 6th of 1996.
- For the PSP remake of the game's release in North America, there were a variety of contests and promotions you could sign up to, namely Chop Chop Master Onion's Rap Showdown, in which you had to submit your cover of one of three songs from the first game and Cheap Cheap's Cook up a Character Contest, in which you had to draw an original character for the franchise and the winner would get a drawing of said character made by Rodney Greenblat himself.
- Despite being for the most part accurate, the English translation of PaRappa the Rapper has a few typos, such as with Jet Baby being referred incorrectly on the intro scene and PaRappa being spelled with two Rs at one point during stage 4's cutscenes.
More shall come in the future...
