Make a Christmas pet overlay for your stream

Turn a pet photo into a festive mascot you can keep in your OBS scene all December. Give it a small wave for a Twitch follow and a bigger celebration for a TikTok LIVE gift.

Generation uses credits. Custom characters need Ultra to react to real live events.

Set up your Christmas pet in OBS

Choose a look. Use a clear photo of your pet, then describe an original outfit. Start with one accessory such as a red scarf so the face and fur markings stay recognizable.
Create two Reactions. Start with a quiet Idle for the scene and a Heart or Cheer to thank viewers. Preview both with the same outfit before going live.
Add and test the overlay. Paste the private overlay URL into an OBS Browser Source. Place it away from captions and game UI, then test a supported event from your connected streaming platform.

For a portrait scene, keep the mascot away from the bottom of the frame where controls can cover it. In TikTok LIVE Studio, follow the Link source setup guide.

Grinch Pet video or Christmas stream mascot?

The Grinch Pet AI template on CapCut is for making a short video. StreamRio lets you make an original holiday pet that sits in your live scene and can react again whenever a configured event happens. Milo’s look is a StreamRio example, not a Grinch preset.
