Outside of NiGHTS, Puffy made a cameo in Sonic Adventure as a card in the NiGHTS pinball stage and in Sonic and All Stars Racing Transformed as a obstacle. Puffy also appeared in Sonic Pinball Party and in the Nightmare Zone DLC of Sonic Lost World as a boss. Her theme was also an unlockable music track in Sega Superstars Tennis.
The main gist of NiGHTS' battle with Puffy is that you must grab her and throw her into the wall at the end of the stage.
Upon flying up to her, NiGHTS will automatically grab her and start spinning her. The object from here is aiming her onward, into the next room.
Having Puffy hit you will take time away from your timer, giving you less time to defeat her and eventually giving you a Night Over.
Puffy's level consists of six rooms resembling a house. There is a bedroom, dining room, and bathroom. Stairs can also be seen on the back wall in the dining room. Along the walls of Puffy's level are many paintings of Nightmaren minions and one of herself. The portrait of Puffy is actually an original concept drawing.
There is a set of double doors in the very last room, as well as a shelf. You defeat Puffy by pushing her under the shelf, breaking the support causing her to get smashed between the wall and the tumbling shelf.
On rare occasions, the doors in the last room open just as Puffy is being defeated. Inside is a lamp-post like object which falls out and onto the floor. No one has discovered why this happens or what triggers it.It most likely happens at random, and is similar to the guillotine in Jackle's level dropping seemingly at random.
A translated Japanese bio for Puffy states:
"A rubber ball-like Second-Level, her body is pliable and flexible. Because of this, NiGHTS’s attacks don’t seem to work on her. Maybe somewhere around that mansion she created there’s a clue to defeating her."
The BGM for Puffy's level is called "She Had Long Ears" and involves opera-like singing. If you put the Sega Saturn disc into a CD player, Puffy's BGM will be track 7.
- In Christmas NiGHTS, if playing the Sonic the Hedgehog mode, Puffy will be replaced by Dr. "Eggman" Robotnik and her theme will be replaced with a remix of the final boss battle theme from the Japanese and European version of Sonic CD.
- Puffy's own name is one of the nicknames of record producer/music industry executive/part-time performing hip hop artist P. Diddy.
- Puffy reappears in the Nightmare Zone DLC of Sonic Lost World, as the Nightmaren that Zazz is riding on.
