Playpen

In all Petz games (except the spin-off Babyz and Petz 5, for some curious reason), including those made before the introduction of actual Playscenes, petz can amble about a wide expanse called the Playpen. Unlike a Playscene proper, it's not make to look like a real-life place - it's just a screen. The screen is covered with a pattern (wallpaper, if you will) that can be changed in General Options.
