You should have a greyed out icon for it.
If not. Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game in a new save.
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.
I tried that even with the mods folder moved to the desktop and the localthumbcache.package deleted in a new file the greyed out icon for Tomarang is still missing.
Try to repair the game. If that doesn't work. Try doing a factory reset as described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199
