Themes
VS Code Pets comes with themes. Themes are set from the VS Code Preferences Window. Search for "vscode-pets" to find the VS Code Pets specific settings.
Configure vscode-pets.theme to "forest" and let your pets play in a spooky forest.

Set vscode-pets.theme to "castle" for them to roam the ramparts!

Set vscode-pets.theme to "beach" for your friends to play by the ocean.

Set vscode-pets.theme to "winter" for your pets roam around the snowy mountains.

If you find the snowfall too distracting, you can disable special effects in settings.
