Princess Robot Bubblegum (プリンセス ロボット バブルガム)
is a fictional anime series featured in the GTA IV Era.

Princess Robot Bubblegum is a general parody of shōjo (young female) anime; however, it incongruously mixes this with tropes of shōnen (young male), seinen (mature male), and hentai (pornographic) anime.
