Newly Downloaded Mods Not Showing on Mod List

[MomOfJeffersonCereal]

I am trying to assist my son with an issue he is having, so please forgive the fact that I don't play this game.

 

We downloaded two new (to us) mods today--Lucky Block and Plants vs. Zombies. Neither is showing in the Mod List. I have tried removing all mods from the mods folder except one of the new ones, updating Forge to the newest version, and using both an unzipped and a zipped version of Lucky Block. Same problem.

 

I added screenshots of the initial problem as well as the mods folder. Can send more if helpful.

 

Does anyone have any other solutions? Thank you!

First off lucky blocks is a zip, thats not right, it should be a jar.

Second off OpenTerrainGenerator should be a jar not a folder.

As for PvZ you'd have to post your log.
