You can use PF2e Token Markers and apply a marker to the token that way.

https://github.com/TikaelSol/PF2e-Animal-Companions/releases/download/5.7.1/module.json is the manifest URL you want for the latest version of the Module that is v10 compatible.

There's a foundry module called PF2e Companion Compendia that has all the Eidolon feats and stuff. Ask your GM to get the module then you can build your eidolon using a PC sheet. Just keep it's health at 0 and manage your joint health with your summoner's sheet.

For companions and eidolons you'll want the PF2e Animal Companions module, which gives you a few new compendia that all start with CC. From there, make a new character sheet (a player character one) and drag over the appropriate Eidolon, Prototype Construct, or Animal Companion Ancestry.

I have videos on the github page showing how to build each companion type.

I did have that module loaded. I needed to watch the videos on TikaelSol's GitHub page to see how to get that done. Thank you, u/Jetanwm!

There is a video with instructions on the github page.

GitHub - TikaelSol/PF2e-Animal-Companions: A module for Foundry VTT that enables automation with PF2e Animal Companions.

There is a module for managing animal companions - PF2e Animal Companion Compendia. It essentially provides a few additional compendiums that add actions, ancestries, and feats for animal companions. You make the animal companion using a regular PC character sheet, but instead of choosing "Elf" or "Human", etc., you choose "Bear" or "Cat".
