I have read the Imsposta Q and A stuff, and either missed it or its not in there. Anyone have any ideas?

What did you do to “show the critter?” It won’t automatically add a creature to Extras if that’s what your trying for, the player will still have to add it directly. What “critter” is it? A homebrewed one or a standard creature? Where isn’t it “showing” it?

You gotta give me more details for me to help. 

Mithril Tiger. This polished mithril tiger can become an [Tooltip Not Found] for up to 24 hours every 7 days. The [Tooltip Not Found] fights only to defend itself and you. Once it has been used for 24 hours, it can't be used again until 7 days have passed.

Added this to the description box. It does not show a clickable link like this does:

Critter is a homebrew one:

Those “clickable links” are called “tooltips.” You can find your answers in the General FAQ #9: (https://www.dndbeyond.com/forums/dungeons-dragons-discussion/homebrew-house-rules/131411-a-homebrewers-how-to-faq).

I hope that helps.
